White Kaolin Clay By Vishnu Mineral Industries

With
the combination of technology and skilled team, we are engaged in manufacturing, supplying and exporting premium quality
White Kaolin Clay. This mineral is a hydrated aluminum
silicate and found in partly decomposed granite, which is an igneous
feldsparic rock. Widely used in the production of paints, paper,
plastic, electrical and cosmetic & soap, this clay can be availed
in different packaging options. Our quality analyzers test White
Kaolin Clay on below mentioned parameters:

• Effectiveness
• Purity
• Composition
• Shelf
  life

Other Details:

Chemically, kaolin is a hydrated aluminium silicate containing Al₂O₃.2SiO₂.2H₂O. It is one of the most abundantly available clay in the Earth's crust. It is a soft, earthy, usually white to off white and sometimes reddish in colour, produced by the chemical weathering of aluminium silicate minerals like feldspar.
