800 mesh washed kaolin for papermaking high whiteness
Kaolin has a range of applications which are grouped in three main areas: paper,ceramics andrefractories.
Demand is most in the manufacture of paper where it performs two separate functions- as a filler to improve printing characteristics and as a coating pigment to enhance the surface properties of the paper such as the brightness, smoothness, gloss and ink receptivity etc.
In the ceramics industry the main function of kaolin is to impart whiteness . Its major uses are in vitreous china sanitaryware, table ware, wall tiles, electrical porcelain…
Kaolin is used in refractories where it is valued for its alumina content.
Performance mineral applications use kaolin as fillers in paint, rubber , plastics and adhesives and sealants and pharmaceuticals.
Other important uses include the manufacture of white cement and glass fibre.
