Kaolin is a non-metallic mineral,

Kaolin is a kind of non-metallic mineral. It is a kind of clay and clay rock dominated by kaolinite group clay minerals. It is named after the white clay used to make porcelain produced in Gaoling Village, Jingdezhen, Jiangxi Province. Pure kaolin is white, delicate, soft soil, with good plasticity and fire resistance and other physical and chemical properties. Its mineral composition is mainly composed of kaolinite, Eloite, hydromica, illite, montmorillonite, quartz, feldspar and other minerals.

1, ceramics and porcelain manufacturing: kaolin in ceramics and porcelain manufacturing has an important application. Because kaolin has a high melting point and fire resistance, it can stabilize and improve the physical properties and color of porcelain during firing. Kaolin can also increase the strength and plasticity of ceramic ceramics, making it easier to form and carve.

 2, plastics and rubber industry: kaolin as a filler is widely used in plastics and rubber industry. Kaolin can increase the hardness, rigidity and wear resistance of plastic and rubber products. At the same time, due to the adsorption properties of kaolin, it can also improve the processing properties of plastics and rubber, and improve the quality and performance of products.

3, paint and ink production: kaolin is widely used in paint and ink production. Kaolin has good thickening, dispersion and settlement resistance, and can be used to adjust the viscosity and rheological properties of coatings and inks. Kaolin also provides a whitening effect and enhances the covering power and gloss of paints and inks.

4, building materials: kaolin can be used in the preparation of building materials. For example, kaolin can be mixed with cement, stone and other materials to make lightweight insulation, fillers and coating bases. Kaolin's ability to absorb water also gives it potential for regulating building humidity and improving indoor air quality.

 5, medicine and cosmetics: kaolin in the medicine and cosmetics industry also has a certain application. Because of the high adsorption capacity of kaolin, it can be used to prepare drug sustained release agents and drug adsorbents to improve the stability and bioavailability of drugs. In cosmetics, kaolin can be used as an ingredient to regulate the texture of products and provide oil absorption capacity.
