Product Performance of Niobium Carbide NbC Powder CAS 12069-94-2:
Niobium carbide is a dark grey-brown powder with a cubic crystal structure and metallic luster. It is stable at 1000 ~ 1100℃ and rapidly oxidized to niobium pentoxide above 1100℃.
Niobium carbide is a kind of material with a high melting point and hardness.
Niobium carbide is insoluble in hot and cold hydrochloric acid, sulfuric acid, nitric acid, soluble in hot hydrofluoric acid and nitric acid mixed solution.
Niobium carbide is a commonly used as carbide additive, which is easy to be fused into titanium carbide, zirconium carbide, tungsten carbide, and other compounds, and forms homogeneous solid solution mixture together.
