The main characteristics of nano vanadium carbide ultrafine vanadium carbide powder prepared through a special process, nano vanadium carbide VC = 62.95, carbon content of 22% of the black metal-like powder, the crystallization of a sodium chloride type cubic crystal system, lattice constant 4.182 Å , boiling point, melting point 28000C, 39000C, good chemical stability and high temperature performance. Can be used for cutting tools, steel-making industrial and tungsten carbide grain refiner alloys, can significantly improve. As the VC and other rare metal carbide added to suppress the alloy grain growth and improve the organizational structure as the main purpose, whether it is the production of coarse grain, such as mining tools or round bars, such as ultra-fine grain alloy, they should choose a low Fsss carbides of rare metals, rare metal carbides due to the added small amount of it is just starting to adjust the WC grain size and improve the role of organizational structure, and therefore, I hope additives finer dispersion of the more Haojiu Hang. Rods and other ultra-fine grain alloy if the additive is too rough, but the formation of alloy folder coarse, unfit to improve the performance of the material. I sold the nano vanadium carbide powder, the particle size to nanoscale, the proportion of added to the general ten thousandth can greatly improve the performance of the material. Vanadium carbide as a grain refiner, has been widely used in steel and other industries, high purification, nano nano vanadium carbide, its application to further expand with the development of science and technology, have been widely used in cemented carbide and catalytic materials many fields, is a combination of vanadium and titanium resources development and production of an important class of high value-added new materials.
Applications
A cutting tool, the steel industry and the tungsten carbide grain refining agent, can significantly improve the alloy properties.
