Abstract: Silica-coated lead chromate pigments having improved stability in use under abrasive conditions are prepared by processes in which the lead chromate pigment particles, in a liquid slurry, are subjected to intense shear to break up agglomerates, and are thereafter coated with dense silica, optionally in combination with alumina.
