Titanium Ti Powder CAS 16962-40-6

About Titanium Ti Powder:
Titanium powder is a kind of metal powder with a wide range of uses. Titanium powder is a silver-gray irregular powder, has a large suction capacity, high temperature or sparks under the condition of flammable. Titanium powder metallurgy (P/M) offers the possibility of manufacturing clean - or near-clean - shaped parts without the material losses and costs associated with machining complex parts from forged billets. Powders can be elemental blending or pre-alloying and then cured by metal injection molding, hot isostatic pressing, direct powder rolling, or laser engineering mesh forming.
Among the metallic elements, titanium has high specific strength. It is a high-strength but low-mass metal and has fairly good ductility (especially in the absence of oxygen). The surface of titanium is silvery-white metallic luster. Its melting point is quite high (over 1,649 degrees Celsius), so it is good refractory metal. It is paramagnetic and its electrical and thermal conductivity are very low.
Titanium, which has two allotropes, transforms from the hexagonal most densely packed α type to the body-centered β type at 882 degrees Celsius. The specific heat of type α increases sharply with increasing temperature until it reaches the critical temperature, but decreases when it reaches the critical temperature, and then remains essentially constant for type β regardless of temperature. Like zirconium and hafnium, titanium also has a ω-state that is thermodynamically stable at high pressure but may also be isostatically stable at atmospheric pressure. This state is generally hexagonal (ideal) or triangular (twisted) and can be observed when soft P-wave acoustic photons cause the plane collapse of a β-type (111) atom. Biomedicalmaterialsprogram is a trusted global Titanium Ti Powder supplier. Feel free to send an inquiry about the latest price of Titanium at any time.
Titanium has a considerable hardness, though not as strong as higher-grade heat-treated steels. Titanium is non-magnetic and is a poor conductor of heat and electricity. Mechanical handling needs to be careful, because, without sharp tools and proper cooling techniques, titanium will soften and leave an indentation. Like steel structures, titanium structures have a fatigue limit, which ensures durability in some applications. The specific stiffness of titanium alloy is generally not as good as other materials such as aluminum alloy and carbon fiber, so it is rarely used in structures requiring high stiffness. 

Features of Titanium Ti powder CAS 16962-40-6:

How is Titanium Ti Powder produced?
The traditional titanium production technology is through the Kroll process, that is, in the presence of carbon in the presence of chlorinated titanium dioxide ore, TiCl4 generated by the reaction with magnesium to form titanium sponge. These processes occur at temperatures up to 1040°C. The particle size range of sponge particles is 45 ~ 180 μm, and the particle size within 150 μm is called "sponge particles".These tiny particles are irregularly shaped, porous, spongy and then the fine powder is mixed with an alloy additive; The green compaction was cold-pressed at 415 MPa and then vacuum-sintered at 1260 ° C to produce components of 99.5% density. Hot isostatic pressing (HIP) can further increase the density of these parts, making it more economical to produce parts than casting or forging parts, but the porosity present in the material reduces fatigue and fracture properties.
 
Applications of Titanium Ti Powder:
Titanium powder is used in pyrotechnic manufacturing to provide bright burning particles.
Titanium powder is also used in air purifiers (filter coatings), and in the film that is attached to building Windows that, when exposed to ultraviolet light (solar or artificial) or moisture in the air, produces highly reactive REDOX species, such as hydroxyl groups, that clean the air or keep window surfaces clean.
Titanium is used to make propeller shafts, rigging and heat exchangers in desalination plants because it is not easily corroded by seawater. Titanium powder is also used in cold water heaters in saltwater aquariums, fishing lines and diving knives. Titanium is used to make housing and other components for Marine surveillance deployments, as well as for scientific and military surveillance devices.
 

Storage Conditions of Titanium Ti powder:

The damp reunion will affect its dispersion performance and using effects, therefore, this product should be sealed in a vacuum and stored in a cool and dry room and it should not be exposure to air. In addition, the Titanium Nanoparticles should be avoided under stress.

How is Spherical Graphite C Powder produced?
Spherical graphite is produced through fine grinding, purification and sterilization. It is made of flake graphite concentrate produced from graphite ore.
Generally, flake graphite is shaped into a spherical shape by a mechanical grinding process. The round shape of graphite allows particles to be more efficiently accumulated in the LiB anode, thereby increasing the energy and charging capacity of LiB.
Then the spheroidized graphite is purified to eliminate harmful elements, including SiO2, Fe, S and other metal elements. Various purification techniques are used. These measures include the use of hydrofluoric acid for active acid purification and the use of high-temperature furnaces for thermal purification. Both methods have their advantages and disadvantages.
Active acid purification is a means and an effective purification method, but due to the nature of the acids used (including hydrofluoric acid), there are toxic and dangerous working environments and environmental management challenges. Thermal purification is an electric heating process. Compared with acid purification, it is very expensive, but it is very safe and does not affect the environment.
After purification, please use purified spherical graphite to help improve the surface area and surface area of the particles. Many LiB manufacturers use their own proprietary technology for coating.
The purified spherical graphite is then packaged into the anode shape required for LiB batteries.

Graphene has excellent optical, electrical and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedical and drug delivery, etc., and is considered a revolutionary material in the future.
Single-layer graphene
What is graphene a single layer of? Graphene is a single layer (monolayer) of carbon atoms, tightly bound in a hexagonal honeycomb lattice. It is an allotrope of carbon in the form of a plane of sp2-bonded atoms with a molecular bond length of 0.142 nanometres. Single-layer Graphene refers to a two-dimensional carbon material consisting of a layer of carbon atoms that are periodically packed together in a benzene ring structure (i.e., a hexagonal honeycomb structure).
Graphene (few-layer)
What is few layer graphene? Graphene (few-layer) refers to a two-dimensional carbon material composed of 3-10 layers of carbon atoms stacked in a benzene ring structure (i.e. hexagonal honeycomb structure) in different stacking ways (including ABC stacking, ABA stacking, etc.).
Multilayer graphene
Multilayer graphene, also known as multi-layer graphene, refers to a two-dimensional carbon material composed of the benzene ring structure (namely hexagonal honeycomb structure) with a thickness of more than 10 layers and less than 10nm and the carbon atoms stacked periodically and closely in different stacking ways (including ABC stacking, ABA stacking, etc.).
Single-layer graphene has emerged as a high-performance material capable of replacing outdated technologies, benefiting countless industries. Graphene is very light, but it's very durable, and it's able to conduct high levels of electricity through very small amounts of material. Applications for graphene include small electrical circuits and sockets, medical devices, and solar cells. Because of its flexibility, many industry leaders have started using graphene to ensure the safety of their various devices without compromising their efficiency. Single-layer graphene has proven to be a very reliable resource that is both economical and energy-efficient.
Single-layer graphene of the ACS material is available in powder or dispersed form. Single-layer graphene powders are produced using a combination of thermal peel reduction and hydrogen reduction. The monolayer graphene dispersions were created using our own mechanical stripping and dispersion methods. Both products do not contain metal ions and can be used as a conductive agent to improve the high rate of charge and discharge capacity of the battery. In addition to batteries, single-layer graphene powders and dispersants are used in supercapacitors, lead-acid batteries, solar cells, semiconductor chips, graphene films, coatings, and many biological materials.Biomedicalmaterialsprogram is a trusted global Single And Multi Layer Graphene Powder supplier. Feel free to send an inquiry about the latest price of Graphene at any time.
Graphene layers consist of ultra-thin layers of carbon atoms arranged in a hexagonal honeycomb lattice. Graphene films produced by chemical vapor deposition (CVD) are polycrystalline in nature, with multiple small graphene domains growing and merging into a continuous film. Compared to single-layer graphene, fewer layers have the potential to develop into materials or heterostructures -- by inserting different substances into their layered structures. 

How is Single And Multi-Layer Graphene Powder Produced?
The common powder production methods of graphene are the mechanical stripping method, REDOX method, SiC epitaxial growth method, and chemical vapor deposition (CVD) method.
Dispersible monolayer graphene was prepared by complete reduction of GO prepared by Hummer method. Commonly used preparation methods can produce denser graphene, which tends to aggregate. The resulting graphene clumps are insoluble in water or other polar solvents and can no longer disperse, making further treatment difficult. Our dispersible graphene avoids this problem and can be re-dispersed in many solvents.
 
Applications of Single And Multi-Layer Graphene Powder:
With the gradual breakthrough of mass production and large size problems, the industrialized application of graphene is accelerating. Based on the existing research results, the first fields to achieve commercial application may be mobile devices, aerospace, new energy batteries. With a unique combination of novel electronic, optical and mechanical properties, graphene-based nanomaterials have found applications in energy generation and storage. For example, they are used in basic research, transmission photovoltaic devices, transistors and batteries, new energy batteries, sensors and flexible electronic devices, aerospace fields, photodetectors and biomedical applications (such as drug delivery, biological imaging and tissue engineering), etc.
The research and application development of graphene continue to heat up. Graphene and graphene-related materials are widely used in battery electrode materials, semiconductor devices, transparent display screens, sensors, capacitors, transistors and other aspects. Due to the excellent performance and potential application value of graphene materials, a series of important advances have been made in many fields such as chemistry, materials, physics, biology, environment, energy and so on. Researchers are trying different methods in different fields to produce high-quality, large-area graphene materials. And through the continuous optimization and improvement of the preparation process of graphene, the preparation cost of graphene can be reduced so that its excellent material properties can be more widely used, and gradually toward industrialization.

Storage Condition of Graphene Powder:
The damp reunion will affect graphene powder dispersion performance and using effects, therefore, graphene powder should be sealed in vacuum packing and stored in cool and dry room, the graphene powder can not be exposure to air. In addition, the graphene powder should be avoided under stress.

Selenium powder Se powder CAS 7782-49-2

About Selenium powder Se powder:
Selenium powder, chemical formula Se, black gray nonmetal, soluble in concentrated sulfuric acid, chloroform, slightly soluble in carbon disulfide, toxic, insoluble in water, ethanol. Selenium powder is usually in the form of powder or granule, with pure appearance, consistent color, purity up to 99.99%, no soil and other impurities, stable composition and even moisture.
Selenium is a chemical element with the symbol Se and an atomic number of 34. It is a nonmetal (much less thought of as a nonmetal), somewhere between sulfur and tellurium on the periodic table, and also similar to arsenic. Selenium is found in metallic sulfide ores, where it partially displaces sulfur. Commercially, selenium is a by-product of the refining process of these ores, usually during the production process. Pure selenium or selenate compounds are known but are rare. Today the main commercial uses for selenium are glassmaking and pigments. Selenium is a semiconductor used in photovoltaic cells. The once important applications of electronic products have been largely replaced by silicon semiconductor devices. Selenium is still used in several types of DC power surge protectors and one type of fluorescent quantum dot. Biomedicalmaterialsprogram is a trusted global Selenium powder Se powder supplier. Feel free to send an inquiry about the latest price of Selenium powder at any time.
Although trace amounts of selenium are necessary for cellular function in many animals (including humans), the elements of selenium and (especially) selenium salts are toxic in even small doses, leading to selenium poisoning. Selenium is an ingredient in many multivitamins and other dietary supplements, as well as infant formula, and is a component of the antioxidant enzymes glutathione peroxidase and thioredoxin reductase (which indirectly reduce certain oxidizing molecules in animals and some plants) and three diiodide enzymes. 

Features of selenium Se powder CAS 7782-49-2: 
Amorphous red powder, becoming black on standing and crystalline on heating; vitreous and colloidal forms may be prepared. Amorphous form softens at 40 °C and melts at 217 °C. It rarely occurs in its elemental state in nature, or as pure ore compounds. Soluble in concentrated nitric acid and in (liquid form) common alkalies. Forms binary alloys with silver, copper, zinc, lead, etc. Low toxicity. A necessary nutritional factor for animals.

How is Selenium powder Se powder Produced?
Selenium is a kind of sparse element, and there is no independent selenium production plant in the world. Selenium is associated with electrolytic copper and nickel, which exists in anode mud of electrolytic anode. There are many methods to recover and purify selenium and tellurium from copper electrolytic anode mud, such as caustic oxidation pressure leaching, oxidation roasting high-temperature leaching, low-temperature oxidation roasting, dilute sulfuric acid leaching, etc. Selenium and tellurium are reduced mostly by sulfur dioxide reduction and copper reduction. Due to the method of pre-roasting and oxidation, the maintenance cost of complex power equipment is high, the sulfur dioxide gas is harmful to the human body and the environment, and the recovery and purity of selenium and tellurium are high. With H2O2 as oxidant, selenium and tellurium were oxidized in a weakly acidic solution. After solid-liquid separation, selenium and tellurium were separated by adjusting pH, and selenium and tellurium were reduced by Na2SO3 under hydrochloric acid acidification. The recoveries of selenium and tellurium were 99% and 98%, respectively, and the purity of both of them could reach 99%.

Applications of Selenium powder Se powder:
Selenium can be used in different fields, depending on its purity. Selenium is now used in a wide variety of applications, from glass and metallurgy to pigments, agriculture and electronics. Selenium powder is mainly used in the production of selenium dioxide as electrolytic manganese melting catalyst, other applications in rectifier, photographic exposure agent, petroleum working catalyst, copy toner cartridge, selenium photosensitive plate, alloy, feed and pigment in plastics, paint, enamel and glass, medical and health care medicine and other industries.

Storage Condition of selenium Se powder:
The damp reunion will affect Se powder dispersion performance and using effects, therefore, selenium Se powder should be sealed in vacuum packing and stored in cool and dry room, the selenium Se powder can not be exposure to air. In addition, the Se powder should be avoided under stress.
