A simple method for dissolution of tantalum pentoxide.
A simple and reproducible procedure has been developed for the dissolution of tantalum pentoxide. The oxide is fused with potassium nitrate and potassium carbonate in the ratio of 2:5:5. The cooled melt is dissolved in concentrated sulphuric acid. If a tartaric acid solution is desired the sulphuric acid is evaporated and the residue dissolved in 20% tartaric acid solution.
