Product description

Pure niobium block for sale
Niobium is a gray-white metal with a melting point of 2468 ° C, a boiling point of 4742 ° C, and a density of 8.57 grams per cubic centimeter. Niobium is stable in air at room temperature and does not oxidize completely at red heat in oxygen. It can be directly combined with sulfur, nitrogen and carbon to form alloys with titanium, zirconium, hafnium and tungsten at high temperature. It does not react with inorganic acids or bases, nor is it soluble in aqua regia, but soluble in hydrofluoric acid.
