Tantalum Nitride TaN Powder CAS 12033-62-4

About Tantalum Nitride TaN Powder:

Tantalum nitride is a kind of chemical material. The Tantalum nitride formula is TaN, and its molecular weight is 194.95. Materials used to create precise sheet resistors that are resistant to water vapor. During the manufacture of integrated circuits, these films are deposited on top of the silicon wafer to form a thin film surface mount resistor. Tan tantalum nitride is a black hexagonal crystal. The relative density is 13.4; the melting point is 3090℃; the microhardness is 1100kg/mm2, the thermal conductivity is 9.54W/(m·K), and the resistivity is 128μΩ·cm.

Tantalum nitride is a yellow-green crystal of sodium chloride type with a relative density of 15.6. The lattice constants are A =0.4336nm and C =0.4150nm. The melting point was 2950℃, the microhardness was 3200kg/mm2, and the conversion point temperature was 17.8K.

Insoluble in water and acid, slightly soluble in aqua regia, soluble in potassium hydroxide, decomposed to release ammonia, heated to 2000℃ to release nitrogen.

Product Performance of Tantalum Nitride TaN Powder:

The molecular formula of tantalum nitride is TaN, and the molecular weight is 194.95. Tantalum nitride is insoluble in water and acid, slightly soluble in aqua regia, soluble in potassium hydroxide, and decomposed to release ammonia, and it releases nitrogen when heated to 2000°C.

How is Tantalum Nitride TaN Powder Produced? 

1. Tantalum powder is directly nitriding with nitrogen or ammonia at about 1100℃;

2. Tantalum nitride is prepared using tantalum and nitrogen as raw materials. The reaction formula is as follows: 2Ta+N2= 2TaN.

Applications of Tantalum Nitride TaN Powder:

Tantalum nitride 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 treatment (about 20nm), copper is first covered with tantalum, and then TaN is coated by physical vapor deposition (PVD). Before machining (grinding/polishing), the barrier-coated copper is coated with more copper through PVD and then filled with electrolytic-coated copper.

Tantalum nitride is also suitable for thin-film resistors, which can form a moisture-resistant passivation oxide film compared with nickel-chromium resistors.

Materials used to create precise sheet resistors that are resistant to water vapor.

Tantalum nitride can be an additive for super hard materials to produce pure tantalum pentachloride, which can spray and increase the electrical stability of transformers, integrated circuits, and diodes.
