Tantalum-Niobium Carbide TaNbC

Description

Tantalum Niobium Carbide TaNbC, dark grey color, is a solid solution powder of tantalum carbide and niobium carbide by carbonizing and solutionzing process, melting point 3686°C. With the characteristics of zirconium carbide and niobium carbide, it is a high temperature structural material with high melting point, high hardness, high strength, corrosion resistance, good thermal conductivity and good toughness, and has stable chemical properties with no odor, no toxic, no corrosive and insoluble in water. Tantalum Niobium Carbide TaNbC solid solution powder can be extensively used as raw material applied in hard alloys industry for the production of cemented carbide tools as an additive to effectively inhibit the grain growth of hard alloys. Tantalum Niobium Carbide is also usually used for the preparation of refractory material, high-temperature, wear-resistant and spraying material, welding material, high-temperature radiation resistant material, metal ceramic material, high-temperature vacuum devices in mechanical processing, electronic information, metallurgy and minerals, aerospace and other industry fields.
