Potassium fluorotitanate method: Potassium fluorotitanate and sulfuric acid heated to 400 ° C, the reaction water to boiling, the dilution of the acidification solution was hydrolyzed to produce hydrous oxide precipitate, and then separated, washed, dried, pentoxide Tantalum two finished.
2K2TaF7 + 2H2SO4 + 5H2O → Ta2O5 + 2K2SO4 + 14HF
2 metal tantalum oxidation method: the metal tantalum tablets dissolved in nitric acid, hydrofluoric acid mixed acid, extracted and purified with ammonia precipitation tantalum hydroxide, and then washed, dried, burned, ground, tantalum pentoxide Finished product
3Ta + 5HNO3 + 21HF → 3H2TaF7 + 5NO + 10H2O
H2TaF7 + 7NH4OH → Ta (OH) 5 + 7NH4F + 2H2O
2Ta (OH) 5 → Ta2O5 + 5H2O
