Tantalum nitride is a hexagonal gray crystal. Relative density 13.4; melting point 3090 ℃; thermal conductivity 9.54W / (m · K), resistivity 128μΩ · cm, microhardness 3200kg / mm2, transformation point temperature 17.8K. Do not dissolve in water, acid, slightly soluble in aqua regia, soluble in potassium hydroxide and decomposition to release ammonia. Heated to 2000 ℃ to release nitrogen. Materials used to make accurate sheet resistance, tantalum nitride resistance is resistant to water vapor erosion. Used as a superhard material additive for spraying, increasing transformer, integrated circuit, diode’s electrical stability.
