The Essential of Kaolin in Paint and Coatings Industry
Kaolin Clay is a hydrated silicate aluminium crystalline material, which is produced over millions of years by the hydrothermal decomposition of granite minerals, or 'china clay,' as it is widely called. It is a soft, earthy, usually white mineral which in many parts of the world is colored pink-orange-red by iron oxide. Sometimes, alternating layers are found.

Kaolin applications in ceramics
Acceptable iron levels in kaolin differ depending on the end use. Levels of up to 0.7% Fe 2 O 3 can be tolerated but lower levels are required for material used in bone china where translucency is more important. In general, the iron content of kaolin used in ceramics should be below 0.5%. The presence of titania should also be very low.
