Application of tantalum pentoxide
Tantalum pentoxide, also known as “tantalum anhydride”, is a white rhombic crystal. Its chemical properties are more stable, resistant to general acid and alkali, when heated by hydrogen chloride or hydrogen bromide erosion. The corresponding insoluble tantalate can be obtained by co-melting with the hydroxide of alkali metal or carbonate, which is hydrolyzed by washing with water to produce hydrated tantalum pentoxide precipitate. At present, the traditional high purity tantalum pentaoxide is prepared by the tantalum liquid in the [...]
