Abstract

The hydrolysis of a solution of a titanium salt such as the sulphate is effected after addition of titanic hydroxide which has been precipitated and then dispersed or peptised. The dispersion, which preferably has a pH value less than 2 and is capable of passing through filter paper but not through a collodion membrane, may be prepared by boiling a dilute solution of a titanium salt, washing the precipitate and dispersing it with an acid such as nitric acid. The hydroxide precipitated by the process may be wholly dispersed, a part be used for the hydrolysis of another batch of solution, and the remainder be worked up for use as a pigment.
