Silicon Dioxide SiO2 is a raw material for manufacturing glass, quartz glass, water glass, optical fiber, important components of the electronic industry, optical instruments, handicrafts and refractory materials, and is an important material for scientific research.

When Silicon Dioxide SiO2 is crystallized, it becomes crystal; Silicon Dioxide SiO2 becomes agate after gelation and dehydration; Silicon Dioxide SiO2 becomes opal after solidification of water-containing colloid; Quartzite. It is a mineral resource with very stable physical and chemical properties. The crystal belongs to the oxide mineral of the trigonal system, that is, low-temperature quartz (α-quartz), which is the most widely distributed mineral species in the quartz group. Quartz in a broad sense also includes high temperature quartz (beta-quartz). Quartz block, also known as silica, is mainly the raw material for the production of quartz sand (also known as silica sand), as well as the raw material for quartz refractories and sintering ferrosilicon.
