Tantalum pentoxide (Ta2O5) CAS1314-61-0 is a white colorless crystalline powder, which is the most common oxide of tantalum and the final product of tantalum combustion in air. Mainly used for pulling lithium tantalate single crystals and manufacturing high refractive and low dispersion special optical glasses, it can be used as a catalyst in chemical industry.

Specification

Chinese name: Tantalum pentoxide

Foreign names: tantalic oxide, tantalum pentoxide

CAS: 1314-61-0

Structure or molecular formula: Ta2O5

Molecular weight: 441.89

Density: 8.2g/cm3

Melting point (℃): 1800

Character: White rhombic crystal, rhombic columnar body

Dissolution: Soluble in molten potassium bisulfate and hydrofluoric acid, insoluble in water and other acids

Toxicity: Dust has a irritating effect on the respiratory mucosa, and long-term exposure to dust can lead to pneumoconiosis. The maximum allowable concentration of tantalum oxide is 10mg/m3. When working in environments with high dust content, it is necessary to wear gas masks and prevent the emission of oxide dust. The crushing and packaging processes should be mechanized and sealed.

Application

Raw materials for producing tantalum metal. Also used in the electronics industry. Used for pulling lithium tantalate single crystals and manufacturing high refractive and low dispersion special optical glasses, it can be used as a catalyst in chemical industry.

Packing

25kg/drum
