Silicon dioxide

Silicon dioxide

Silicon dioxide (chemical formula: SiO₂) is an acidic oxide, and the corresponding hydrate is silicic acid (H₂SiO₃). Silica is one of the most important compounds of silicon. The natural silica that exists on the earth accounts for about 12% of the mass of the earth's crust, and its existing forms are divided into two categories: crystalline and amorphous, collectively referred to as silica
