ABSTRACT:
Hydrolysis of a titanyl sulphate solution is carried out according to the autonucleation method of gradually adding the solution to a body of water at a substantially constant rate over 10-20 minutes, in such a way as to obtain an ionic concentration after one minute of feeding of from 75 to 105 g/l, the concentration of sulphuric acid in the final hydrolysis solution being regulated to a value of from 310 to 330 g/l by adding water from the commencement of clouding of the hydrolysis solution up to the end of hydrolysis.
