Kaolin / China Clay
Formula : Al2Si2O5(OH)4
Description
Kaolin Kaolinite also known as China Clay is a soft, earthy, usually white mineral (dioctahedral phyllosilicate clay), produced by the chemical weathering of aluminium silicate minerals like feldspar.
At RMCL's China Clay continues to be a highly valuable raw material in both traditional and modern applications. Also processed or refined kaolin is available in white powder form, granule cum powder form, and in lumps form.
