    The Properties And Application of Titanium nitride

    The titanium nitride structure (TiN), which is similar to that of NaCl, has a lattice constant, a = 0.4241 nm. Titanium-atoms are found at the corners tops of this face-centered cubic. TiN has a nonstoichiometric composition, which is TiN0.37 - TiN1.16. Changes in nitrogen content are possible within a specified range, without affecting the structure of TiN. The TiN powder has a yellowish-brown color, while ultrafine powders are black and the TiN crystals have a golden yellow colour. TiN has an excellent thermal shock resistance, a melting temp of 2950degC and a density of 5-4.44g/cm3. TiN has a much higher melting temperature than most of the transition metals, but it also has a lower density. This makes TiN a heat-resistant metal. The TiN crystal is very similar to TiC. However, the C atoms are replaced with N atoms.
    Nature Introduction

    TiN is an extremely stable compound. It will not reacted with metals, such as iron and chromium at high temperature. Also, TiN crucibles won't react with acidic Slag in CO and N2 atmospheres. It can be used with alkaline or acidic slag. TiN, when heated under vacuum, loses nitrogen and becomes titanium nitride that has a lower nitrogen content.

    TiN is attractively golden in color. It also has a very high melting temperature, a good chemical stability, and a low wetting ability to metals. It is a superconductor with high electrical conductivity. It is also superconducting material.

    Uses of Titanium Nitride Ceramic Materials in Biomedicine

    What is titanium Nitride?

    Titanium-nitride is a non-stoichiometric compound. Its stable composition range is TiN0.37-TiN1.16, and the nitrogen content can be changed within a specific range without causing changes in the structure of the TiN. TiN, a nonstoichiometric material, has a range of stable compositions between TiN0.37 and TiN1.16. Nitrogen contents can also be adjusted within this range without altering the TiN structure. The TiN Powder is usually yellow-brown. The ultrafine TiN Powder is black. TiN Crystals are golden-yellow. TiN has melting points of 2950degC and a density between 5.43-5.44g/cm3. It also has a Mohs Hardness of 8-9 as well as high thermal shock resistance. TiN's melting point is higher than the melting points of most transition-metal nitrides. The density of TiN is lower than the majority metal nitrides. This makes it a material that is very heat resistant. The TiN crystallization is very similar in structure to TiC. However, the C atoms have been replaced by N atoms.

    Titanium Nitride as a Biomedical Material

    Clinical medicine has widely used the occluder for the treatment of congenital diseases, such as the atrial septal defect, ventricular septal defect and patent arteriosus. Most common concentrics occluders contain nickel up to 55% in nickel-titanium metal alloy materials. The body can become poisoned and allergic to nickel, which in turn may cause cancer. The surface membrane of the occluder Nickel-Titanium alloy may be damaged, and internal nickel ions released in the complex human environment can increase nickel content. This further deteriorates the tissue compatibility.

    According to relevant studies, because titanium nitride is a biocompatible material (which was previously used in coronary-stents), thrombus formation is lower than with nickel-titanium. To address this problem, scientists developed a Cera Ceramic Membrane Occluder, using high-energy coating technology. It maintains both the original interventricular and atrial septal septal occluder designs based on nickel-titanium occluders. The design of the occluders and patent arteriosus devices uses plasma technology in order to evenly coat the surface of nickel-titanium alloy powder with a titanium nitride (TiN) film. The metal coating of titanium and C,N,O and other compounds is transformed by ion technologies into the biological layers. This layer improves corrosion resistance and compatibility between biological tissues and human blood. The comparison of the data from animal experiments shows that the Cera membrane occluder has a much higher performance in terms cell creeping growth than a nickel-titanium standard occluder. It significantly reduces thrombosis risk and helps repair congenital heart defects. Platelet adhesion rates and hemolysis are also lower compared to the nickel-titanium standard occluder. Cera's occluder was approved by other countries, including the European Union, India and Brazil. The Cera occluder has been used by more than 2,000 patients with congenital hearts disease.

    Titanium nitride Characteristics and Application

    What is Titanium nitride (TiN)? Titanium Nitride (TiN) is a very hard ceramic, sometimes called Tinite, that's used to improve the surface properties of aluminum, titanium alloys, carbide steels, and other substrates.
    The thin coating of TiN, due to its golden color, is used as a protective and hardening layer for cutting and sliding surfaces. In addition, it can also be used as an exterior surface for medical implants that are non-toxic. In the majority of applications, a thin coating less than 5 millimeters is applied.

    Titanium Nitride Characteristics
    Titanium Nitride's Vickers hardness is 1800-2100. It has a 251 GPa modulus, a 9.35x10-6 K-1 thermal expansion coefficient, and a 5.6 K superconducting threshold temperature.
    Titanium Nitride is oxidized at 800 degrees Celsius in normal air. Titanium Nitride appears golden when coated and has a brownish color. Laboratory tests show that it is chemically inert at 20 degC. However, with increasing temperatures, concentrated acid solutions can slowly attack the material. Titanium Nitride has a coefficient friction of 0.4-0.9, depending on its surface finish and substrate. The typical TiN structure is NaCl type with a 1:1 stoichiometry. However, TiNx with x between 0.6 and 1.2 is thermodynamically stabile.
    TiN superconducts at cryogenic temperature, with critical temperatures as high as 6.0 K in single crystals. Superconductivity in thin-film TiN has been studied extensively, with the superconducting properties strongly varying depending on sample preparation, up to complete suppression of superconductivity at a superconductor-insulator transition. After a thin layer of TiN had been chilled to almost absolute zero, it was transformed into the world's first superinsulator. Its resistance increased by a factor 100,000.

    Titanium nitride Applications
    TiN coated drill bit
    Gerber pocketknife coated with dark gray TiCN
    It is well known that TiN The coating improves the lifetime of machine tooling such as milling and drill bits by up to three times.
    TiN's metallic golden color is used for decorative purposes to cover costume jewelry and automobile trim. TiN can also be used on door and plumbing hardware as a decorative top-layer, often with nickel or chromium-plated substrates. It's used as a protective coating for aerospace and military purposes, and on the suspension forks in bicycles and motorbikes, as well as shock shafts in radio-controlled vehicles. As it is so durable, TiN can also be used to coat the moving components of semi-automatic weapons and rifles. The coating is not only extremely durable but also very smooth. This makes removing carbon build-up a breeze. TiN, which is non-toxic and meets FDA guidelines has been used to coat medical devices, such as orthopedic bone saw blades and scalpel knives, when edge retention and sharpness were important. The TiN coatings were also used to coat implanted medical implants (especially hip implants) and prostheses.
    Although thin films are not as visible, they still have a similar effect. TiN In microelectronics they are used as diffusion barriers to stop the diffusion of metals into silicon. TiN is classified in this context as a “barrier metal” (electrical conductivity 25 uO*cm), despite the fact that it is clearly ceramic when viewed from a chemistry and mechanical perspective. Recently, chip design for 45 nm and beyond has also used TiN to improve transistor performance. In conjunction with gate dielectrics such as HfSiO has a greater permittivity than SiO2 and can therefore be used to reduce gate lengths with low leakage. TiN thin films may also be used to coat zirconium-alloys to create accident-tolerant nuclear fuels.
    TiN layers can be used for electrodes as well in bioelectronics applications, such as in intelligent implants and in-vivo sensors that must resist the corrosion caused by bodily fluids. TiN electrodes have already been applied in the subretinal prosthesis project as well as in biomedical microelectromechanical systems (BioMEMS).

    Titanium nitride is a refractory compound with high microhardness and chemical and thermal stability

    What is titanium Nitride? Titanium Nitride is a refractory with high chemical and heat stability. TiN can be used for many purposes: as part of special refractory material and cermets. It is also a good crucible in metal anoxic casts. In a study of the combustion of titanium samples that were compacted and dissolved in nitrogen, it was found that the rate at which nitrogen is filtered out of the titanium was the most important factor. Titanium sponges are a cheaper, more convenient and purer source of titanium.
    How can titanium nitride be used?
    The PVD (physical vapor deposition) process produces a gold ceramic coating on the metal surface. The coating is hard and low friction, and it has a moderate resistance to oxidation. The coating is smooth and does require any post-painting.
    TiN is commonly used on machine tools to improve their corrosion resistance and maintain the edges.

    TiN, which is golden in color, can be used for decorating costume jewelry or car accessories. It is also used widely as a top-coat on consumer sanitary items and door hardware. This is usually done using a nickel (Ni), or chromium, plated substrate. It is used in aerospace and military applications, to protect the sliding surfaces found on front forks for bicycles and motorbikes, as well as the shock-absorbing shafts for radio-controlled vehicles. As TiN is extremely durable, it is also used on moving parts for many semi-automatic and automatic firearms. The coating is very smooth, which makes it easy to remove carbon deposits. TiN, which is FDA compliant and non-toxic has been used on medical equipment, such as orthopedic bone saw blades and scalpels where edge retention and sharpness were important. TiN coatings were also used to coat implanted medical implants, such as hip replacement implants.

    TiN film, although not as visible, is used in microelectronics as a conductive contact between active devices, such as circuits and metal contacts, as well as as a barrier for metal diffusion. silicon. Although TiN is a ceramic material from a mechanical or chemical point of view in this case, it is classified a "barrier-metal" (resistivity less than 25 uO*cm). TiN can also be used in the latest chip designs (45 nm or higher) to improve transistor performances. When combined with a gate-dielectric that has a higher dielectric coefficient than standard SiO2 such as HfSiO, the gate length is reduced while maintaining low leakage. A TiN coating is also being considered for zirconium-alloys that resist accidental nuclear fuel.

    TiN electrodes can be used for bioelectronic devices, including smart implants, in-vivo biosensors and other bioelectronic devices, due to their high biological stability. They must also withstand the severe corrosion that occurs from body fluids. TiN electrodes have been used in subretinal prosthesis projects and biomedical microelectromechanical systems (BioMEMS).

    Which is better? Titanium or titanium Nitride?
    For materials that are softer, such as wood or plastics, titanium alloy bits can be a good choice. While the type of titanium coated is different. As an example, titanium nitride and titanium carbonitride are more effective at treating harder materials. Titanium, an element and metal, is composed of nitrogen and titanium.

    Is titanium Nitride toxic?
    Titanium Nitride, also called Tinite, is a very tough ceramic material that's used to improve surface properties on titanium alloys and steel components.
    TiN is used for a thin, protective coating on cutting and sliding surfaces. Due to its golden coloration, it can also be used for decorative purposes and to provide a nontoxic surface for medical implant. In many applications, the thickness of the coating is less that 5 microns. The study concluded the material tested was not toxic, irritant, hemolytic, or biocompatible.

    How strong is Titanium Nitride?
    feature. The Vickers hardness is 1800-2100. The elastic modulus of TiN, is 251 GPa. The tiN oxidizes at 800degC. Normal atmosphere.

    Other advanced uses of titanium nitride

    1. Plasma Titanium Nitride Promotes Indium Oxide CO2 Photocatalysis .
    Photothermal titanium nitride (TiN) is a nano-scale metal material capable of capturing sunlight across a broad spectrum and generating a higher temperature locally through its photothermal effects. Indium oxide-hydroxide nano-scale material, In2O3x(OH)y, is a semiconductor capable of photocatalytic hydrogenation of gaseous CO2. The wide electron gap of In2O3-x(OH)y limits its ability to absorb photons in the ultraviolet range of the solar spectrum. This article combines two nanomaterials into a ternary heterstructure: TiN at TiO2 and In2O3 -x(OH). This heterogeneous structural material synergistically combines metal TiN with semiconductor In2O3(OH)y via the interface semiconductor, TiO2. The conversion rate of photo-assisted reverse gas shift reaction will be much higher than the single component or binary combination.

    2. Li-S battery polysulfide adjustments can be made by dissolving the vanadium within the titanium nitride frame.
    The ability to adapt the chemistry of host-guest interactions is very important, but has not been applied effectively to lithium-sulfur battery (Li-S). Here, a unique titanium-vanadium-vanadium nitride (TVN) solid solution fabric was developed as an ideal platform for fine structure adjustment to achieve efficient and long-lasting sulfur electrochemistry. It is shown that by dissolving vanadium in the TiN structure, it can be used to adjust the electronic and coordination structure of Ti and Vanadium. This will change their chemical affinity toward sulfur species. This optimized TiV interaction provides the highest polysulfide capacity and helps to firmly fix sulfur and accelerate reaction kinetics. After 400 cycles of cycling, the Li-S battery has a capacity retention as high as 97%. The reversible surface capacity can also be maintained under high sulfur loads of 6.0 mcg cm-2, and an electrolyte with a concentration of only 6.5 mL/g-1. This study provides a new perspective for future rational adjustments of high-quality Li-lithium batteries.

    Is Lead Carbonate Soluble in Water?

    Lead carbonate, PbCO3, is a mineral composed of orthorhombic crystals. It decomposes at about 315degC, producing toxic fumes and reacting violently with fluorine to produce a fire hazard.

    Lead is a toxic metal and can cause severe health problems, including comas or death in children. It is also thought to cause hearing loss and IQ problems in children.

    Water soluble leads include lead(II) acetate, lead(II) carbonate, and lead metaborate (Pb(CO3)22-). These are important industrial chemicals used in the production of colored glazes, white house paints, and tin-lead plating applications.

    Various sets of batch dissolution experiments have been conducted to investigate the impact of pH values ranging from 7.0 - 9.5, temperatures (5@C vs. 20@C) and alkalinity levels (moderate vs. low) on the solubility of lead species in drinking water.

    The results of these experiments have shown that pH ranging from 7.0 to 9.5 has no significant influence on the dissolution of lead species. In addition, cold temperature and moderate alkalinity showed a great influence on decreasing the solubility of lead species.

    Inhalation of lead carbonate can lead to a variety of health problems such as respiratory tract irritation, sore throat, and lead lines in the gums. Exposure to lead can also be a serious health risk for pregnant women. It can have long-term effects such as lowered IQ, behavioral disorders, and seizures.
