Kaolin | AMERICAN ELEMENTS
Kaolin (china clay) is a hydrated aluminium silicate crystalline mineral (kaolinite Al 2 Si 2 O 5 (OH) 4 ), formed over many millions of years by the hydrothermal decomposition of granite rocks. Rocks that are rich in kaolin or kaolinite are known as china clay or white clay.Web

Material Development Potential of Nigeria's Kaolin
The clay has poor plasticity and high refractoriness. Primary clay is mostly composed of a micro-crystalline kaolinite compound (Al 2 O 3 .2SiO 2 .2H 2 O) [ 40 ]. Kaolin is a lightweight, soft sedimentary rock, having chalk-like properties and an earthy odour. It is made up of about 90% kaolinite mineral [ 41 ].Web
