Tantalum carbide, TaC in chemical formula, light brown metallic cubic crystalline powder, belongs to sodium chloride cubic crystal system. Insoluble in water, insoluble in inorganic acid, soluble in hydrofluoric acid and nitric acid mixed acid and can be decomposed. Tantalum carbide has good chemical stability and strong oxidation resistance, and is easy to be melted and decomposed by potassium pyrosulfate. High electrical conductivity.
Tantalum carbide powder is usually synthesized from tantalum pentoxide and carbon black in an inert or reducing atmosphere. The products with high density and metallic luster can be made by hot pressing sintering method.
Used as an adjunct to aerospace materials and hard alloys. Used in powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear resistant alloy tools, tools, molds and wear resistant structural components additives, improve the toughness of alloy. The sintered body of tantalum carbide shows golden color and can be used as an ornament for watches. Tantalum carbide sintered grain growth inhibitor has obvious effect on grain growth inhibition.
Our company has successfully developed ultrafine tantalum carbide with the laser particle size D50 less than 3 microns, reaching the leading level of tantalum carbide in China. Tantalum carbide company adopt method of high temperature vacuum sintering production process, not only the product of high purity, high degree of alloying, monthly production capacity can reach more than two tons, and long-term supply to the domestic each big enterprises, but also increased the international market of propaganda, has sales of international clients, after using this company produces the tantalum carbide, are given the consistent high praise.
