Tantalum Pentoxide

Tantalum pentoxide is white powder, which is stable and very hard to melt. It is mostly common oxide of tantalum, which is also final product for tantalum firing in air. Its chemical properties are close to niobium pentoxide. Tantalum oxide is insoluble in water, ethyl alcohol and mineral acid, however soluble in hydrofluoric acid.
