Calcined Kaolin Clay Is a kind of nonmetallic minerals, is a kind of kaolinite mineral clay and clay rock. the pure Kaolin Powder is white and fine, soft soil, it has good  plasticity and fire resistance.Its mineral composition mainly consists of kaolinite, halloysite, hydromica, illite and montmorillonite, quartz and feldspar mineral composition.Kaolin Clay application is very extensive, mainly used for paper making, ceramics and refractory materials, secondly used in paints, rubber filler, enamel glaze and white cement raw material, a few used in plastics, paint, paint, grinding wheel, pencil, daily cosmetics, soap, pesticide, medicine, textile, oil, chemical industry, building materials, and so on!
