Diatomaceous earth is a type of siliceous rock mainly distributed in countries such as China, the United States, Japan, Denmark, France, Romania, etc. It is a biogenic siliceous Sedimentary rock, mainly composed of the remains of ancient diatoms.

Contains a small amount of Al2O3, Fe2O3, CaO, MgO, K2O, Na2O, P2O5, and organic matter. SiO2 usually accounts for over 80%, with a maximum of 94%. The iron oxide content of high-quality diatomaceous earth is generally 1-1.5%, and the aluminum oxide content is 3-6%. The mineral composition of diatomite is mainly Opal and its varieties, followed by clay minerals hydromica, Kaolinite and mineral debris. The mineral debris includes quartz, feldspar, Biotite and organic matter.

Diatomaceous earth is composed of amorphous SiO2 and contains small amounts of Fe2O3, CaO, MgO, Al2O3, and organic impurities. Diatomaceous earth is usually light yellow or light gray, soft, porous, and lightweight. It is commonly used in industry as insulation materials, filtering materials, fillers, grinding materials, water glass raw materials, decolorizing agents, diatomaceous earth filter aids, catalyst carriers, etc.

Advantages of using diatomaceous earth: pH neutral, non-toxic, good suspension performance, strong adsorption performance, light bulk density, oil absorption rate of 115%, fineness ranging from 325 mesh to 500 mesh, good mixing uniformity, no blockage of agricultural machinery pipelines during use, can play a moisturizing role in the soil, loosen the soil quality, extend the effective fertilizer time, and promote crop growth. Compound fertilizer industry: Compound fertilizer for various crops such as fruits, vegetables, flowers and plants. Advantages of using diatomaceous earth: diatomaceous earth should be used as an additive in cement. Diatomaceous earth coating additive products have the characteristics of high porosity, strong absorption, stable chemical properties, wear resistance, heat resistance, etc. They can provide excellent surface performance, compatibilization, thickening, and improved adhesion for coatings. Due to its large pore volume, it can shorten the drying time of the coating. It can also reduce the amount of resin used and reduce costs. This product is considered to be an efficient coating matte product with good cost-effectiveness, and has been designated as a product by many large international coating manufacturers, widely used in water-based diatomaceous mud.
