China clay is a naturally occurring white clay that is primarily composed of the mineral kaolinite. It is widely used in the ceramics industry due to its excellent plasticity, whiteness, and ability to be easily shaped and molded. China clay is a crucial component in the production of porcelain, earthenware, and other ceramic products, where it enhances the strength, smoothness, and translucency of the final products.

Ceramics: China clay is extensively used in the production of porcelain, earthenware, and stoneware. Its primary role is to provide the necessary plasticity, improve the strength, and enhance the whiteness and translucency of the ceramic products.

Paper: It is used as a filler and coating material in the paper industry, helping to improve the brightness, smoothness, and printability of paper products.

Paints and Coatings: China clay is used in paints and coatings to provide opacity, improve the texture, and enhance the durability of the coatings.

Rubber and Plastics: Used as a filler to improve the mechanical properties, enhance the appearance, and reduce the cost of rubber and plastic products.
