Abstract

290,684. Spence & Sons, Ltd., P., and Crundall, S. F. W. Nov. 17, 1926. Pigments are prepared by reacting an insoluble titanium phosphate with a base in the form of an oxide, hydroxide, or salt of a volatile or weak acid such as a carbonate. The phosphate may be treated in suspension with a solution or suspension of the base, preferably by boiling, and the product be calcined; or the phosphate and base may be mixed intimately in a dry state, and the mixture be calcined. When a soluble or readily fusible phosphate, such as sodium phosphate, is obtained be the reaction, it may be washed out with water; when, on the other hand, an insoluble phosphate, such as calcium phosphate, is obtained, this may either remain in the product, or be removed by a dilute acid, as desired. By treating a mixture the titanium phosphate and barium sulphate a white pigment may be obtained; and by using as the base, ferric or chromium oxide, coloured pigments result. In examples, a mixture of basic titanium phosphate and ferrous sulphate is calcined at 700-800‹ C. to give a red pigment, and a mixture of basic titanium phosphate, barium sulphate, and ammonium bichromate is calcined at 700-800‹ C. to give a green pigmer.t.
