Typical applications of Ta2O5

• For single crystal and high purity applications
• For sputtering targets, high sinter activity
• For optical applications
• For carbides, ceramics, electroceramics (MLCC, Piezoceramics, Ferrites) , pigments
• For metal tantalum, alloy additives, superalloys. 

 We supply 99.9% and 99.99% purity grade tantalum pentoxide (Ta2O5) produced by T.I.C members smelters in China
