Quartz is the main composition of the crust in nature, its chemical composition is mainly silicon dioxide, another contains a small amount of impurities, such as aluminum trioxide, iron oxide, calcium oxide, magnesium oxide, titanium oxide and so on.
Quartzite can be divided into two types: sedimentary and metamorphic. The former has no obvious boundary between clastic particles and cement, while the latter refers to the quartz ore with deep and pure metamorphism.Gangue quartz is formed by hydrothermal action, almost entirely composed of quartz, compact block structure.
The mineral content of quartz sand varies greatly, mainly quartz, followed by feldspar, mica, rock debris, heavy minerals, clay minerals and so on.
Some of them exist as silicate compounds, forming various mineral rocks.The other part exists as a separate mineral entity.
The appearance of quartz varies with different types. The content of gangue quartz and quartzite silica, which are commonly used as ceramic raw materials, are more than 99% and 97% respectively.
Gangue quartz for dense block crystal state or solidification into glass state, and the vein shape output, mostly white, milky white or gray, opaque or translucent, hard texture, section with glass luster or grease luster, the surface is often stained with varying degrees of rust.Quartzite is a compact solid mass with slightly more impurities than gangue.
Quartz is the basic raw material of silicate industry and also the indispensable raw material in ceramic production.
