Kaolin Clay

Product Name :
Kaolin Clay

Kaolin (china clay) is a hydrated aluminum silicate derived from the mineral Kaolinite.

Kaolin is chemically inert clay with a low shrink-swell capacity, well-suited to a wide range of industrial uses including ceramics, paper, glass fiber, filler, paints, wire and cable and plastics.

 

Washed Kaolin: OG-71 and OG-60

Our OG series kaolin mined from China is a mixture of halloysite and kaolinite with some illite.

OG series kaolin deposit is characterized by low Fe and Ti level which make it very suitable for ceramics, especially porcelain.
