Thermal Processing and Chemical Treatment. Thermal processing (calcination) consists of high-temper-ature fi ring of wet- or dry-processed kaolin in either a rotary or a vertical kiln. Calcination increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles.Web
