China Clay

CHINA CLAY

China Clay is also known as hydrated Aluminium Silicate. China clay, one of the purest of the clays, composed chiefly of the mineral kaolinite usually formed when granite is changed by hydrothermal metamorphism. It is one of the most abundant clay available in the earth crust. It is light weight and super white in color. It has high degree of brightness, low plasticity, ease of dispersion and good oil absorbtion.
Chemically China Clay is known as  Aluminium Silicate (Al2O3.2SiO2.2H2O)
