Potassium Titanisulphate, K2Ti(SO4)3, is produced by melting together titanic oxide and potassium pyrosulphate.
The alkaline earth salts, CaTi(SO4)3, SrTi(SO4)3, and Ba2Ti3(SO4)8, are formed when TiO2 dissolved in concentrated sulphuric acid is mixed with a sulphuric acid solution of the corresponding sulphate and the resulting solution is concentrated. These salts are decomposed by water with precipitation of titanic acid. |
