Product Description

Product Description

Silicon dioxide, an inorganic compound with the chemical formula SiO2, is a long-range ordered arrangement of silicon and oxygen atoms to form crystalline silicon dioxide and a short-range ordered or long-range disordered arrangement to form amorphous silicon dioxide. 
Silicon dioxide has the chemical formula SiO2 and is available in both crystalline and amorphous forms. 
Silicon dioxide has a wide range of uses, mainly used in the production of glass, water glass, pottery, enamel, refractory materials, aerogel felt, ferrosilicon, type sand, monomorphous silica, cement, etc. In ancient times, silicon dioxide was also used to make glaze and carcasses for porcelain.
