Kaolin Powder From South Africa

详情

Kaolin (also known as china clay) is a white, soft, plastic clay mainly composed of fine-grained plate-like particles. It is chemically inert, non-abrasive and has low heat and electricity conductivity. Plastic clays have a wide range of colours, but when fired, selected clays give results that are pure white. Plastic clays are used in the production of fine ceramics, for filling and coating of paper and in many other markets.
