Kaolin

Kaolin

image(4)Kaolins are relatively pure clays composed essentially of kaolinite. Kaolins are used to modify the ball clay properties, primarily to control and adjust the casting rate of the ceramic body.

The main properties given to the body are:

  • Cast rate
  • Rheological stability
  • Improves the whiteness of the body
  • Adds alumina and improves resistance to deformation
