What is the difference between diatomite and kaolin? Thank you
The special porous structure of natural diatomite can be observed under microscope, and the microstructure of diatomite is the characteristic of physical and chemical properties of diatomite.
Diatomite is composed of amorphous SiO2 and contains a small amount of Fe2O3, CaO, MgO, Al2O3 and organic impurities. Diatomite usually pale yellow or pale gray, soft, porous and light industry often used as insulation materials, filter materials, fillers, abrasive materials, water glass raw materials, decoloring agent of diatomite filter agent, catalyst carrier etc..
The main component of kaolin is 2Si02 2H20 Al203, is the most dense or loose soil. Easily dispersed in water or other liquids, soapy, earthy. Having plasticity; wet soil can be molded into various shapes without breaking, and can remain unchanged for a long time. Is a kind of non metallic minerals is ubiquitous in nature, are used to produce ceramic, refractory materials and a small amount of mixed plastics, rubber filler in law. It is widely used in ceramics, rubber, plastics, artificial leather, cement, refractory materials, chemical industry and agriculture.
