图标Product description:

The chemical properties of tantalum oxide are rhombic columnar bodies. The relative density is 8.2. Melting point 1872℃±10℃.

Soluble in molten potassium hydrogen sulfate and hydrofluoric acid, insoluble in water and other acids, insoluble in water, acid and alkali (except hydrofluoric acid), it is an amphoteric compound, reacts with alkali to generate various oxo acid salts, such as LiTaO3, KTaO3 , Sr2Ta2O7, etc.; Tantalum exists in the form of cations in acidic solutions, such as TaOPO4, Ta2(SO4)5, etc.



The product is in powder form, white or light yellow, and is mainly used in the production of tantalum powder, tantalum bar and tantalum carbide.

Used in the production of ordinary ceramic piezoelectric ceramics and ceramic capacitors. And the production of optical glass additives and tantalate crystals.
