Kaolin belongs to a kind of non-metallic mineral. Its texture is pure white and delicate, soft soil-like, and has very good fire resistance and plasticity. Kaolin has a wide range of uses, and it is mainly used in refractory materials, ceramics, papermaking and other fields. Secondly, it is used in industrial sectors such as pencils, daily cosmetics, soap, pesticides, medicine, textiles, petroleum, chemicals, building materials, and national defense.
Physical and chemical properties of kaolin:
1. Characters: much dull, white and fine when pure, gray, yellow, brown, etc. when it contains impurities. Depending on the origin, the appearance can be loose soil mass and compact rock mass;
2, Density: 2.54-2.60 g/cm3;
5. With plasticity, wet soil can be molded into various shapes without breaking, and can remain unchanged for a long time
Our type: calcined kaolin, washed kaolin, metakaolin.
Calcined kaolin and washed kaolin, also known as porcelain clay, It has high whiteness, high fineness, good plasticity, and has strong corrosion resistance and good durability. It is an excellent raw material for making ceramics and rubber, paper so on.
Metakaolin is a highly active mineral admixture. It is an amorphous aluminum silicate formed by calcination of ultrafine kaolin at low temperature. It has high pozzolanic activity. It is mainly used as a concrete admixture and can also be used for high-performance geological polymerization.
