Product Description

Silica gel is a kind of high-active absorbing material, which is generally obtained by reaction of sodium silicate and sulfuric acid together with aging, acidic soaking and other series of post-processing. Silica gel belongs to amorphous substance and its chemical formula is mSiO2 . nH2O. With stable chemical property, it won't burn and won't dissolve in any solvent except for alkali and hydrofluoric acid. Silica gels of various models form different fined-pore structures owing to different manufacturing
