Silicon dioxide has a wide range of applications. Crystals in nature can be used to manufacture important components of the electronics industry, optical instruments, and handicrafts. Silicon dioxide is an important raw material for manufacturing optical fibers. Generally pure quartz can be used to make quartz glass. Quartz glass has a very small coefficient of expansion, equivalent to 1/18 of ordinary glass, and can withstand drastic temperature changes. It has good acid resistance (except for HF), so quartz glass is often used to manufacture high-temperature resistant chemical instruments. Quartz sand is commonly used as a raw material for glass and building materials.

In the semiconductor field, it plays a crucial role as a mask, passivation and protective film for chips, electrical isolation film, and component in modern silicon-based microelectronic chip manufacturing.

In the field of papermaking, as a filler, it can improve the whiteness of paper, reduce its weight, and is suitable for high-speed printing; It is also a good pigment for color spray paper coatings.
