Calcined Kaolin High Whiteness Use for Ceramic Glaze

Calcined kaolin higher whiteness use for ceramic glaze

Kaolin has a range of purposes which are grouped in 3 major areas: paper, ceramics and refractories.

Need is most in the manufacture of paper where it performs two separate functions- as a filler to boost printing qualities and as a coating pigment to enhance the area properties of the paper such as the brightness, smoothness, gloss and ink receptivity etc.

In the ceramics business the primary purpose of kaolin is to impart whiteness . Its major employs are in vitreous china sanitaryware, desk ware, wall tiles, electrical porcelain #8230

Kaolin is employed in refractories where it is valued for its alumina content.

Overall performance mineral programs use kaolin as fillers in paint, rubber , plastics and adhesives and sealants and prescription drugs.

Other EPTant uses incEPT the manufacture of white cement and glass fibre.
