High Purity Tantalum Pentoxide Ta2O5 CAS 1314-61-0 For Special Optical Glass

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.

    product detail

    Name: Tantalum pentoxide, Tantalum(V) oxide                                        Molecular formula: Ta2O5

     

    CAS: 1314-61-0                                                                                         Molecular weight: 441.89

     

    Description: Tantalum pentoxide is a white crystalline powder, which is the most common oxide of tantalum. It is also the final product of combustion of tantalum in air. It is soluble in molten potassium bisulfate and hydrofluoric acid, and insoluble in water and other acids. Tantalum pentoxide can be prepared by potassium fluotantalate method. The process is to heat potassium fluotantalate and sulfuric acid to 400 ℃, add water to the reactant to boil, hydrolyze the acidification solution through full dilution, generate hydrated oxide precipitation, and then separate, wash and dry to obtain tantalum pentoxide product.
