Tantalum pentoxide is a white crystalline powder that is the end product of tantalum combustion in the air. It has the characteristics of strong bond energy, high melting boiling point, chemical stability, insoluble in water, in addition to hydrofluoric acid almost all acids are insoluble.Tantalum pentoxide is widely used in many fields. In the electronics industry, it can be used to manufacture special optical glasses with high refraction and low dispersion and lithium tantalate single crystals. In addition, tantalum pentoxide can also be used as a chemical catalyst, and for the preparation of tantalum metal and other related materials.
