Tantalum Nitride Properties

Tantalum nitride is a black hexagonal crystal. The relative density is 13.4; the melting point is 3090℃; the microhardness is 110kg/m2; the thermal conductivity is 9.54W/(m.K). Resistivity 128u. cm. δ tantalum nitride is a yellow-green crystal, a sodium chloride crystal, with a relative density of 15.6. Character constant α=0. 4336nm, c-0.4150nm, melting point 2950℃, microhardness 3200kg/mm2, transformation point temperature 17.8K. Insoluble in water and acid, slightly soluble in aqua regia, soluble in potassium hydroxide and decomposed to release ammonia. Nitrogen is released when heated to 2000°C.

Tantalum Nitride Method

The metal tantalum powder is directly nitridated with ammonia or nitrogen at about 1100°C.

Overview of tantalum nitride TaN powder

Tantalum Nitride TaN powder is a chemical material with a molecular formula of TaN and a molecular weight of 194.95. Materials used to make precision sheet resistors resistant to water vapor. In the integrated circuit manufacturing process, these thin films are deposited on top of silicon wafers to form thin-film surface-mount resistors. Nitride tantalum TaN powder is a black hexagonal crystal with a relative density of 13.4, a melting point of 3090°C, a microhardness of 1100kg/mm2, a thermal conductivity of 9.54W/(m•K), and a resistivity of 128μΩ•cm.

Tantalum Nitride TaN powder is a sodium chloride type yellow-green crystal, with a relative density of 15.6, a lattice constant of A=0.4336nm, C=0.4150nm, a melting point of 2950℃, a microhardness of 3200kg/mm2, and a transition point temperature of 17.8K.

It is insoluble in water and acid, slightly soluble in aqua regia, and soluble in potassium hydroxide. It is separated to liberate ammonia, and it is heated to 2000°C to liberate nitrogen.

Application of tantalum nitride TaN powder

The material used to make precision chip resistors, tantalum nitride resistors can resist the erosion of water vapor.

Used as a superhard material additive to prepare pure tantalum pentachloride: used for spraying to increase the electrical stability of transformers, integrated circuits and diodes

Tantalum Nitride TaN powder is sometimes used in integrated circuit manufacturing to form a diffusion barrier or "glue" layer between copper or other conductive metals. In the case of BEOL processing (approximately 20 nm), the copper is first covered with tantalum, and then TaN is coated by physical vapor deposition (PVD). Before machining (grinding/polishing), more copper is applied to the barrier coating by PVD, and then electrolytic coating is filled on it.

Tantalum Nitride TaN powder is also suitable for thin film resistors. Compared with nickel-chromium resistors, it has the advantage of forming a moisture-proof passivation oxide film.

Nitride tantalum TaN powder can be used as an additive for superhard materials to produce pure tantalum pentachloride, which can be used for spraying and improving the electrical stability of transformers, integrated circuits and diodes.
