The main characteristics of nano-tantalum carbide ultrafine tantalum carbide powder prepared through a special process, the powder particle size uniformity, easily dispersed, hard and the quality is more important, high chemical stability and good high temperature properties, strong antioxidant capacity, electrical conductivity of the great. Density 14.5g/cm3 melting point 38750C, the boiling point of 55000C. Tantalum carbide ultrafine powders is an important ceramic materials, metal and rare metal carbides TaC, NbC, Cr2C3, VC, added to suppress the alloy grain growth and improve the organizational structure for the main purpose, whether it is the production of coarse grain ultrafine grain alloys, such as mining tools, or round bars should choose a low rare metal carbide particle size is small amount of rare metal carbides because of the added, it just starting to adjust the WC grain size and improve the organizational structure, and thus, hope that the additive effect of the finer the dispersion the more Haojiu Hang. Especially for round bars and other ultra-fine grain alloy, if the additive is too rough, but the formation of alloy folder thick, then of course it is not appropriate.
Applications
1 nm tantalum carbide ultrafine tantalum carbide powder used in powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy additives to improve the toughness of the alloy;
2 nm tantalum carbide ultrafine tantalum carbide powder, tungsten based alloy grain refiner, can significantly improve the alloy properties.
