Product Descriptions：

Silica is a general term for white powdery X-ray amorphous silicic acid and silicate products, mainly referring to precipitated silica, fumed silica and ultrafine silica gel, also including powdered synthetic silicic acid Aluminum and calcium silicate, etc.

Silica is a porous material whose composition can be represented by SiO2·nH2O, where nH2O exists in the form of surface hydroxyl groups. Soluble in caustic alkali and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non-flammable, odorless, odorless, with good electrical insulation.
