Niobium Carbide Powder Features

Niobium Carbide (NbC) Powder is a high-hardness material with good chemical stability and high-temperature performance.

• Insoluble in hot and cold hydrochloric acid, sulfuric acid, and nitric acid.
• Soluble in hot hydrofluoric acid and nitric acid mixed solution. 
• Stable at 1000-1100°C.
• Oxidizing rapidly to niobium pentoxide above 1100°C.
• Easily fused in compounds such as titanium carbide, zirconium carbide, and tungsten carbide, they produce a homogeneous solid solution mixture.

Niobium Carbide Powder Applications

• Used as a hard alloy additive
• Used in producing wear-resistant films and semiconductor films
• Used to prepare carbide tool materials with excellent cutting performance
• Processed into purple artificial gemstones

Niobium Carbide Powder Storage and Packing

Niobium Carbide (NbC) Powder should be sealed and stored in a dry, cool environment with inactive anti-static packaging, avoiding exposure to the air for a long time. The vacuum package is 100g, 500g, 1kg/bag, 50kg/drum, or as required.
