Silicon dioxide Chemical Properties,Uses,Production

Description

Silicon dioxide (chemical formula: SiO2) is a chemical compound comprised of oxide and silicon elements. It is insoluble in water or acids except hydrofluoric acid. It appears as transparent to gray, tasteless crystal which is widely presented in nature as sand or quartz. It is also one of the most abundant mineral existing in Earth’s crust. It has wide applications in various fields as below: (1) as the precursor to glass and silicon; (2) for sand casting; (3) as a additive to food and pharmaceutical products; (4) for production of cement and refractory materials; (5) as the medium for conversion of energy. (6) Extraction of DNA and RNA; (7) as a defoamer component. There are many ways for production of silicon. The most common way is through mining and purification of quartz.
