Product Description

The chemical composition of diatomaceous earth is mainly SiO2, containing small amounts of Al2O3, Fe2O3, CaO, MgO, and organic matter.
The density of diatomaceous earth is 1.9-2.3g/cm3, the bulk density is 0.34-0.65g/cm3, the specific surface area is 40-65 , the pore volume is 0.45-0.98cm ³/g, the water absorption rate is 2-4 times its own volume, the melting point is 1650-1750 ºC, and a special porous structure can be observed under an electron microscope.
The industrial application range of diatomaceous earth as a filler is in the agricultural and pharmaceutical industries, including wettable powders, dry land herbicides, paddy field herbicides, and various biopesticides.
