China Kaolin Powder Supplier & Manufacturer

Kaolin

Kaolin, a non-metallic mineral, is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, it is also called dolomitic soil.

Its pure kaolin is white, delicate, soft and earthy, and has good physical and chemical properties such as plasticity and fire resistance. Its mineral composition is mainly composed of kaolinite, halloysite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals.

Kaolin is usually white and fine, with a soft texture and fine particles (generally between 0.01 and 0.5 microns in diameter), with a large specific surface area and a flaky particle shape.

It exhibits good plasticity, fire resistance, thermal stability, and is not prone to chemical disintegration. Kaolin also has strong adsorption capacity and ion exchange properties. It can adsorb impurities in liquids and gases, and can replace and adsorb cations under certain conditions.
