Product Description
Silicon dioxide (chemical formula: SiO2) is an acidic oxide whose corresponding hydrate is silicic acid (H2SiO3). Silicon dioxide is one of the most important compounds of silicon. The natural silica existing on the earth accounts for about 12% of the mass of the crust, and its existence forms are crystalline and amorphous two categories, collectively known as silica.

Application
Silicon dioxide is the manufacturing of glass, quartz glass, water glass, optical fiber, electronic industry important components, optical instruments, crafts and refractory materials, is an important material for scientific research.
Applications of silica: flat glass, glass products, casting sand, glass fiber, ceramic glaze, sand blasting for rust prevention, sand for filtration, flux, refractory and manufacture of Autoclaved Lightweight Concrete. Silica has many uses. Crystals, which are rare in nature, can be used to make important components in the electronics industry, optical instruments and crafts. Silica is an important raw material for manufacturing optical fiber. Generally pure quartz can be used to make quartz glass. The expansion coefficient of quartz glass is very small, equivalent to 1/18 of ordinary glass, can withstand drastic changes in temperature, good acid resistance (except HF), therefore, quartz glass is commonly used to manufacture high temperature resistant chemical instruments. Quartz sand is commonly used as glass raw materials and building materials.
