Industrial Grade Silicon dioxide with CAS No. 14808-60-7
Silica, pure silica is colorless, it is solid at room temperature, chemical formula is SiO2, insoluble in water. Insoluble in acid, but soluble in Hydrofluoric Acid and hot concentrated phosphoric acid, can work with molten alkalis. It has 2 kinds of crystalline silica and amorphous silica in nature. Silica is widely used in glass making, water glass, pottery, enamel, refractories, aerogel felt, ferrosilicon, molding sand, simple silicon, cement, etc. In food industry, it is used as anti-caking agents, defoamers, thickeners, filter aids, clarifying agents. According to GB2760-2011, it can be used for egg powder, powdered sugar, milk powder, cocoa powder, cocoa butter, vegetable powder, instant coffee, soup powder, etc. The maximum amount used is 15g/kg, powder flavor, the maximum use of 80g/kg, solid drink, the maximum use of 0.2g/kg, food, 1.2g/kg.
