Niobium powder (CAS No. 7440-03-1) is light grey with a high melting point and anti-corrosion. It is used as additives to alloys & raw materials to make welding rods & refractory materials, etc.

Other niobium metals: Niobium Metal Powder, Niobium Foil, Niobium Ingot, etc.

Niobium Powder Description

Niobium powder is steel-gray or silvery-white but takes on a bluish tint when exposed to air at room temperatures for extended periods. The metal's oxidation in air commences at 200°C. Niobium, when used in alloying, improves strength, and its superconductive properties are enhanced when combined with zirconium.
