Silica in nature, such as quartz, quartz sand and so on, is called silica.

Pure quartz is colorless crystal, large and transparent prismatic quartz crystal is called crystal, amethyst is purple with trace impurities, and smoky crystal is light yellow, golden yellow and brown.

Chalcedony, agate and Jasper are all colored quartz crystals containing impurities.

Sand is fine quartz mixed with impurities.

Opal and diatomite are amorphous silica.

Silica is widely used for making glass, water glass, pottery, enamel, refractories, aerogel felt, ferrosilicon, molding sand, silicon and cement.

In ancient times, silicon dioxide was also used to make glaze and carcass of porcelain.

General stone is mainly composed of silica and calcium carbonate.

[2] The melting point of crystalline silica is 1723 ℃, the boiling point is 2230 ℃, and it is insoluble in water.

Except for fluorine gas and hydrofluoric acid, silicon dioxide does not react with halogen, hydrogen halide and inorganic acid, but can dissolve in hot concentrated alkali, molten strong alkali or sodium carbonate.

In addition, silica can be reduced by coke and magnesium at high temperature.

At room temperature, the strong alkali solution and SiO2 will react slowly to form silicate, so the glass bottle for storing the strong alkali solution cannot use the ground glass plug (SiO2 is contained in the glass), otherwise, the viscous sodium silicate Na2SiO3 will be generated, making the plug and the bottle mouth stick together.

Because SiO2 can react with hydrofluoric acid, it can not be contained in glass container.

Silicon dioxide is an important component of glass, quartz glass, water glass, optical fiber, electronic industry, optical instruments, handicrafts and refractory materials, and an important material for scientific research.

[4] When the silica crystal is perfect, it is crystal; when the silica gel is dehydrated, it is agate; when the silica gel containing water solidifies, it becomes opal; when the silica crystal is less than a few microns, it forms chalcedony, chert and secondary quartzite.

The crystal belongs to the oxide mineral of the cubic system, that is, the low temperature quartz (α - quartz), which is the most widely distributed mineral in the quartz group.

The generalized quartz also includes high temperature quartz (β - quartz).

Quartz block, also known as silica, is mainly the raw material for producing quartz sand (also known as silica sand), as well as the raw material for quartz refractories and firing ferrosilicon.
