It is also an extremely important window material for medium-long-wave far-infrared precision guidance and far-infrared imaging, especially in national defense. Military and other cutting-edge technology fields. The applications of Zinc Sulfide are as following:
Luminescent material
Zinc sulfide, coupled with a small amount of suitable activator, has strong phosphorescence and is currently used in various applications from cathode ray tubes to X-ray screens to emit light in dark products. When silver is used as the activator, the resulting color is bright blue with a maximum of 450 nm. The use of manganese produces an orange-red color of about 590 nm. Copper can glow for a long time and has the familiar dark green glow effect. Copper-doped zinc sulfide ("ZnS + Cu") is also used in electroluminescent panels. It also exhibits phosphorescence due to impurities under blue or ultraviolet light irradiation.
Optical materials
Zinc sulfide is also used as an infrared optical material, transmitting from visible light wavelengths to just over 12 microns. It can be used as a flat surface as an optical window or shaped as a lens. It is made of hydrogen sulfide gas and zinc vapor to make microchips and sold as FLIR grade (front looking infrared), in which zinc sulfide is in creamy yellow, opaque form. When hot isostatic pressing (HIPed), the material can be converted into a transparent form of water, called Cleartran (trademark). Early commercial forms were sold as Iran-2, but this name is now obsolete.
Pigment
Zinc sulfide is a common pigment, sometimes called statolith. When combined with barium sulfate, zinc sulfide forms lithopone.
Catalyst
The fine ZnS powder is an effective photocatalyst, generating hydrogen from water when illuminated. Sulfur vacancies can be introduced into ZnS during the synthesis process. This gradually turns white to yellow ZnS into a brown powder and enhances photocatalytic activity through enhanced light absorption.

How is Titanium Sulfide TiS2 Powder produced?
Titanium disulfide is prepared by the reaction of the elements around 500 °C.
Ti + 2 S → TiS2
It can be more easily synthesized from titanium tetrachloride, but this product is typically less pure than that obtained from the elements.
TiCl4 + 2 H2S → TiS2 + 4 HCl
This route has been applied to the formation of TiS2 films by chemical vapor deposition. Thiols and organic disulfides can be employed in place of hydrogen sulfide.
A variety of other titanium sulfides are known.
 
Applications of Titanium Sulfide TiS2 Powder:
The prospect of titanium disulfide as a cathode material for rechargeable batteries was proposed in 1973. Groups IV and V halogen compounds have attracted attention for their high electrical conductivity. The original described battery used a lithium anode and a titanium disulfide cathode. The energy density of the battery is high, the diffusion process of lithium ions to titanium disulfide cathode is reversible, and the battery can be charged.
Titanium disulfide was chosen because it is the lightest and cheapest chalcogenide.
Lithium-ion diffuses fastest in titanium disulfide.
The main problem is the degradation of the cathode after repeated use. This reversible insertion process allows the battery to charge. In addition, titanium disulfide is the lightest and cheapest of all the IV and V groups of layered dihalides.
In the 1990s, titanium disulfide was replaced by other cathode materials (manganese oxide and cobalt oxide) in most rechargeable batteries.
The use of TiS2 cathodes in solid-state lithium batteries most lithium-ion batteries use liquid electrolytes, which can pose safety concerns due to their flammability. A number of different solid electrolytes have been proposed to replace these hazardous liquid electrolytes.
For most solid-state batteries, high inter interface resistance reduces the reversibility of the intercalation process and shortens the service life. For TIS2, these undesirable interface effects are less of a problem. The power density of the all-solid-state lithium battery is 1000 W/kg and the maximum power density is 1500 W/kg in 50 cycles. In addition, the battery's average capacity dropped by less than 10% in 50 cycles. Although titanium disulfide has high conductivity, high energy density and high power, its discharge voltage is relatively low compared to other lithium batteries with high reduction potential cathode.

Molybdenum Disulfide MoS2 Powder CAS 1317-33-5

About Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide (MoS2) is the main component of molybdenite. Black solid powder with a metallic luster. Chemical formula MoS2, melting point 1185°C, density 4.80g/cm3 (14°C), Mohs hardness 1.0～1.5. It starts to decompose at 1370°C and decomposes into metallic molybdenum and sulfur at 1600°C. It starts to be oxidized when heated at 315°C in the air, and the temperature rises and the oxidation reaction accelerates. Molybdenum disulfide is insoluble in water, dilute acid and concentrated sulfuric acid. It is generally insoluble in other acids, alkalis and organic solvents, but it is soluble in aqua regia and boiling concentrated sulfuric acid. Slowly oxidized at 400 ℃ to generate molybdenum trioxide:
2MoS2+ 7 O2→ 2 MoO3 + 4 SO2 can be used to test the generated molybdenum trioxide with ferrotitanium reagent. First, the product is treated with sodium hydroxide or potassium hydroxide solution (the principle is to convert molybdenum trioxide into molybdate), and then the titanium iron reagent solution is added dropwise, which will react with the generated sodium molybdate or potassium molybdate to produce gold Yellow solution. This method is very sensitive, and trace amounts of molybdate can be detected. And if there is no molybdenum trioxide generated, the solution will not produce golden yellow, because molybdenum disulfide does not react with sodium hydroxide or potassium hydroxide solution.
Molybdenum disulfide can react with chlorine when heated to produce molybdenum pentachloride:
2 MoS2+ 7 Cl2→ 2 MoCl5+ 2 S2Cl2
Molybdenum disulfide and alkyl lithium react under control to form an intercalation compound (interlayer compound) LixMoS2. If it reacts with butyllithium, the product is LiMoS2.
Molybdenum disulfide has a high content of active sulfur, which is easy to cause corrosion to copper. It is discussed in many books and papers on lubricant additives. In addition, when the parts made of copper and its alloys need to be lubricated, it is not impossible to use molybdenum disulfide lubricating products, but also to add copper corrosion inhibitors. Feel free to send an inquiry to get the latest price if you would like to buy Molybdenum Disulfide MoS2 Powder in bulk.

Features of Molybdenum Disulfide MoS2 Powder:

3. Can be used for processing and storage of spare parts; Maintenance lubrication adhesion; can form a highly efficient dry lubricating film; Is less wear and friction reduction technology.. 

Analysis of Molybdenum Disulfide MoS2 Powder:

How is Molybdenum Disulfide MoS2 Powder produced?
Natural law
MoS2 can be prepared by the natural method, namely the molybdenite concentrate purification method, which is to remove the acid-insoluble matter in the molybdenite concentrate, SiO2, Fe, Cu, by subjecting high-quality molybdenum concentrate to certain physical and chemical actions. Ca, Pb and other impurities are further refined to obtain nano-MoS2. However, the purity of the nano-MoS2 produced by the natural method is not high, and the purification technology needs to be further improved. When the temperature is lower than 400℃, it is recommended to use the most expensive MoS2 when working in ordinary atmosphere. It has lubricating ability below 1300℃, and it is recommended to use the cost-based MoS2.
Chemical synthesis
The synthetic method can produce sulfides with high purity, less impurities, and fine particle size, and can prepare sulfides that meet different functional requirements. Therefore, the production of nano sulfides by synthetic methods has always attracted much attention. There are many methods for preparing nano-MoS2, such as ammonium tetrathiomolybdate thermal decomposition method, hydrogen sulfide or sulfur vapor reduction method, high-energy ball milling method, carbon nanotube space confinement method, hydrothermal synthesis method, high-energy physical method and chemical method combination and many more.

Applications of Molybdenum Disulfide MoS2 Powder:
Molybdenum disulfide is diamagnetic, can convert linear photoconductors and semiconductors with P-type or N-type conductivity, and has the functions of rectification and energy conversion.
Molybdenum disulfide can also be synthesized as a catalyst for hydrocarbon dehydrogenation.
Molybdenum disulfide is also known as "the king of advanced solid lubricants".
Molybdenum disulfide is a solid powder made from natural molybdenum concentrate chemically purified by changing the molecular structure.
Molybdenum disulfide has good dispersibility and does not need to be added. It can be added to various greases to form a colloidal state and will never replace it, thereby increasing the lubricity and extreme pressure of the grease.
Molybdenum disulfide is also suitable for high temperature, high pressure, high viscosity and high load mechanical working conditions to extend the service life of the equipment.
The main function of molybdenum disulfide as a friction material is to reduce friction at low temperatures, increase friction at high temperatures, and reduce combustion loss. Easily volatilize in the friction material.
Anti-friction: The size of disulfide particles formed by supersonic jet pulverization can reach 325-2500 mesh, the particle hardness is 1-1.5, and the friction coefficient is 0.05-0.1, so it can be used in friction materials to take advantage of the anti-friction effect;
Increased friction: Molybdenum disulfide is not conductive, and silicon carbide, molybdenum disulfide, molybdenum trisulfide and molybdenum trioxide are present. When the temperature of the friction material rises sharply due to friction, the shrinking molybdenum trioxide particles gradually heat up and expand, thereby increasing the friction in the axial direction.
Antioxidant: Molybdenum disulfide is obtained through a comprehensive chemical purification reaction, and its pH value changes 7-8, slightly alkaline. It covers the surface of the friction material, which can protect other materials from oxidation, especially making it difficult for other materials to move and enhancing adhesion.

Storage Condition of Molybdenum Disulfide MoS2 Powder:
Damp reunion will affect MoS2 powder dispersion performance and using effects, therefore, Molybdenum Disulfide MoS2 Powder powder should be sealed in vacuum packing and stored in cool and dry room, the Molybdenum Disulfide MoS2 Powder can not be exposure to air.
