Abstract

Process for the production of improved chromium pigments, characterized in that it comprises treating a chromium pigment, in aqueous suspension, at a temperature higher than 65ºC, with a water-soluble salt of a metal and a water-soluble silicate, being chosen in such a way the mentioned metal so that, in aqueous solution, it forms a water-insoluble silicate.
