What is Diatomite?
Diatomite is composed of amorphous SiO2, and contains a small amount of Fe2O3, CaO, MgO, Al2O3 and organic impurities.
Diatomite is usually light yellow or light gray, soft, porous and light, and is commonly used in industry as insulation materials, filter materials, fillers, abrasive materials, water glass raw materials, decolorizing agents and diatomite filter AIDS, catalyst carriers.
Application of diatomite industrial fillers Pesticide industry: wettable powder, dry land herbicides, paddy field herbicides and various biological pesticides.
As China professional Diatomite Suppliers, We have a sound quality control system, The ready clays we produce have a wide range of applications
