ABSTRACT:
Inorganic oxide pigments (ceramics) are prepared by mixing the starting materials in the presence of water and in the presence or absence of assistants, drying and subsequent calcining in a rotary furnace by processing the starting materials in the presence of water into a pumpable suspension having particle sizes of 50%<10 .mu.m and 100%<50 .mu.m, dewatering the suspension by spray drying it to leave porous granules, and calcining those granules>97% from 20 to 800 .mu.m in size.
