Calcined China Clay Powder is an anhydrous aluminium silicate produced by heating ultrafine natural kaolin to high temperatures in a kiln. The calcination process increases whiteness and hardness, improves electrical properties, and alters the size and shape of the kaolin particles.Production :Calcination occurs in two steps. At 700oC, the de-hydroxylation of kaolin occurs forming a poorly crystalline metakaolin. Products produced at this temperature can improve the dielectric properties of PVC cable insulation. At 980oC an amorphous defect spinel is formed which undergoes a transformation, with mullite recrystallizing in an amorphous glass at temperatures above 1100oC. Products produced within this temperature range provide excellent properties in rubber compounds, improving mechanical properties and chemical resistance. It enhances rigidity, toughness, and dimensional stability.
