What is kaolin used for ?

Kaolin has a range of industrial applications grouped into three main market areas: – Paper, ceramics and specialty minerals. Paper accounts for the majority of sales at around 70% of total sales. It is used in two distinct ways, as a filler between the paper fibres, to improve printing quality and as a coating, to enhance the surface properties of the paper.

Ceramics is the second most important sector, accounting for some 22% of total sales. It is used for the manufacture of sanitaryware, tableware, tiles, electrical porcelain and glazes. Fired brightness, strength and (in sanitaryware) rheological properties are the key parameters for these ceramic whitewares It is also used in refractories where it is of value for its high alumina content. Specialty applications include paint, rubber, plastics, adhesives and sealants and pharmaceuticals, where it is mainly used as a filler.
