Note: We can supply different size products of tantalum carbide powder according to client's requirements.
ultra-fine tantalum carbide powder are prepared by special process method. The powder has uniform particle size, easy dispersion, hard and heavy weight, high chemical stability and good high temperature performance, strong anti-oxidation ability and high electrical conductivity. . The density is 14.5 g/cm3, the melting point is 38750 C, and the boiling point is 55000C. Tantalum carbide ultrafine powder is an important cermet material, which is added as rare metal carbides such as TaC, NbC, Cr2C3, VC, etc., which are mainly used for suppressing alloy grain growth and improving microstructure. For example, mining tools or ultra-fine grain alloys such as round bars should choose rare metal carbides with low particle size. Since the rare metal carbides added are trace amounts, they only serve to adjust the WC particle size and improve the structure of the structure. It is desirable that the finer the dispersion of the additive, the better. Especially for ultra-fine grain alloys such as round bars, if the additive is too thick, the alloy is thicker, which is of course unfavorable.
Application of tantalum carbide Powder:
1 nanometer tantalum carbide and ultrafine tantalum powder are used in powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy additives to improve the toughness of the alloy;
2 nanometer tantalum carbide and ultrafine tantalum powder can be used as grain refiner for tungsten-based hard alloy to significantly improve alloy properties.

Storage conditions:
tantalum carbide Powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
