Product Performance of NbC powder niobium carbide powder:
Niobium Carbide Powder is a green cubic crystal with a metallic luster and is a sodium chloride type cubic system.
The relative density is 8.47, and the lattice constant a = 0.447 nm.
The temperature of 3500 ° C. The microhardness is >23.5 Gpa (>2400 kg/mm2), which is harder than corundum. The elastic modulus is 338000 N/mm2, the coefficient of thermal expansion is 6.65×10^(-6)/K, the thermal conductivity is 14 w/(m·K), the heat of formation is -140.7 kJ/mol, and the specific heat capacity is 36.8 J/(mol·K). The resistivity is 35 μΩ·cm.
Niobium Carbide Powder is insoluble in hot and cold hydrochloric acid, sulfuric acid, nitric acid, and is soluble in a mixed solution of hot hydrofluoric acid and nitric acid. It is stable at 1000 to 1100 ° C, and rapidly oxidizes to ruthenium pentoxide at above 1100 ° C. The niobium carbide is easily melted in a compound such as titanium carbide, zirconium carbide or tungsten carbide, and together forms a homogeneous isomorphous solid solution mixture. Melting point: 3500 ° C, density: 7.6 g / cm 3 (25 ° C)
