Diatomite is formed by remains sediment of single sell water grow plant diatom. The uniqueness of this kind of Diatomite is that it can absorb dissociate silicon in water forming its bones. When its life ends, it deposits and forms Diatomite bed in a certain geological condition. Diatomite belongs to nonmetal mine; its main chemic component is non-crystal silicon dioxide (other name is am orphism opal), attend by a few steatite,kaolinite etc. clay impurity and organic matter. Observing under microscope, Diatomite shows various alga shapes of different forms. Single alga shape size is varying from a little micron to tens of microns; distribute numerous nanometer grade microspores inside and outside. This is the basic physic specialty distinguish from other nonmetals. The industrial area using Diatomite are cannot be separated from its essential specialty of micro multihued structure.

Diatomite has special capability multihued structure, low density, large surface area, strong adsorption capability, good suspend capability, stable instrumental capability, sound insulation and heat insulation, wearable, acid proof, inequity and insipidity. Therefore, Diatomite and its products are extensive used in industry as sewage finishing agent; functional padding; activator carrier; floor sorbet of bad, poisonous, dangerous liquid; environmental protection type dryer of food, medicine, electrical appliances, instruments and costume; filter aid in the process of separating solid and liquid and industrial kiln’ s heat insulation heat preservation material and so on. It can satisfy multifold requests of industry. Diatomite always has the name of “industrial monosodium glutamate”, and it is one of the indispensable basic materials in modern industry.
