China Clay

Kaolin, also called china clay, soft white  and is widely used in the making of Ceramics, paper, rubber, paint, and many other products.

Kaolin is mixed with water in the range of 20 to 35 percent, it becomes plastic (i.e., it can be molded under pressure), and the shape is retained after the pressure is removed. With larger percentages of water, the kaolin forms a slurry, or watery suspension.

​

In the manufacture of whiteware the kaolin is usually mixed with approximately equal amounts of silica and feldspar and a somewhat smaller amount of a plastic light-burning clay known as ball clay. These components are necessary to obtain the proper properties of plasticity, shrinkage, vitrification, etc., for forming and firing the ware. Kaolin is generally used alone in the manufacture of refractories.

Properties of our Kaolin clay in Ceramic Industry

• High fusion temperature

• White burning characteristics

• Particularly suitable for the manufacture of , porcelain, and refractories.

• The absence of any iron, alkalis, or alkaline earths in the molecular structure of kaolinite confers upon it these desirable ceramic properties.
