Niobium carbide powder is a kind of carbide ceramic powder with gray brown appearance and metallic luster. The chemical formula is NbC. The relative density of niobium carbide is 8.47, and the melting point is 3500 ℃. The elastic modulus is 338000 N/mm2, and the thermal expansion coefficient is 6.65 × 10 ^ (- 6)/K, thermal conductivity 14 w/(m · K), resistivity 35 μ Ω·cm。 Niobium carbide is insoluble in cold and hot hydrochloric acid, sulfuric acid and nitric acid, but soluble in hot mixed solution of hydrofluoric acid and nitric acid.

According to different particle sizes, niobium carbide powder can be divided into coarse niobium carbide powder, fine niobium carbide powder, extremely fine niobium carbide powder, ultra-fine niobium carbide powder and niobium carbide nanopowder. We mainly provide ultra-fine niobium carbide powder.
