Niobium Carbide Powder,1.20±0.30μm, Cemented carbide additive, cermet, coating material
Material: Niobium Carbide Powder
Grade: FNbC-1, FNbC-2, NbC-C-3
Appearance: Dark grey powder
Application: The additive of cemented carbide alloy, cermet, coating material, and the material of niobium bar, powder.
Characteristic: Melting point: 3500℃, density: 7.6g/cm (25℃).Microhardness >23.5 Gpa(>2400 kg/mm2), harder than corundum. Insoluble in hot and cold hydrochloric acid, sulfuric acid, nitric acid, soluble in hot hydrofluoric acid and nitric acid mixed solution. It is stable at 1000~1100℃, and quickly oxidized to niobium pentaoxide above 1100℃.Niobium carbide is fusible in titanium carbide, zirconium carbide, tungsten carbide, and so on compounds, and generate a mixture of quasi-isocrystalline solid solution. Therefore, it can be used to make cermet, heat resistant alloy and cemented carbide alloy. It can be used as an additive of cemented carbide, which significantly improves the thermal hardness and thermal resistance of impact, thermal pressure resistance and oxidation resistance. The cutting tools made of TaC also have good thermal hardness, thermal impact resistance and thermal oxidation resistance. At the same time, the composite materials have been widely used in convertor reactor, machining, metallurgy, aerospace and other fields.

Summarize: Niobium carbide, black cubic crystal or purple gray powder. Belongs to sodium chloride cubic crystal system. Insoluble in hot and cold hydrochloric acid, sulfuric acid, nitric acid, only soluble in hot hydrofluoric acid and nitric acid mixed solution;High melting point (3500℃), high hardness (micro hardness > 235GPa, harder than corundum), good chemical stability (stable at 1000~1100℃, rapid oxidation to niobium pentoxide above 1100℃), etc.It is easily fused into titanium carbide, zirconium carbide, and Chemicalbook tungsten carbide, etc., to form a solid solution of homocrystalline, so it can be used to make ceram, heat resistant alloy and hard alloy. It can be used as an additive of cemented carbide to improve its thermal hardness, thermal shock resistance, thermal pressure resistance and oxidation resistance.The cutting tools also have good thermal hardness, thermal impact resistance and thermal oxidation resistance. At the same time, the composite materials have been widely used in convertor reactor, machining, metallurgy, aerospace and other fields.
