Application
Paint industry
Kaolin is used in the coating industry. Because of its white color, cheapness, good fluidity, and stable chemical properties, it has long been used as a filler in coatings and paints. The kaolin used in coatings generally includes washed kaolin and calcined kaolin.
Refractory materials
Kaolin has good fire resistance and is usually used to produce refractory materials. Its products can withstand loads at high temperatures without deformation. The main refractory materials are refractory bricks.
Ceramic industry
Kaolin has become an essential mineral raw material in dozens of industries such as papermaking, ceramics, rubber, chemicals, and coatings.
The ceramic industry is the earliest industry that uses kaolin and uses a large amount of kaolin. The role of kaolin in ceramics is to introduce Al2O3, which is beneficial to the formation of mullite and improves its chemical stability and sintering strength. Kaolin has certain plasticity, adhesion, suspension force and bonding ability, which gives porcelain clay and glaze good formability and facilitates molding. If used in wires, it can enhance insulation and reduce dielectric loss.
