The main component of quartz stone is silicon dioxide (SiO2), which contains about 53.8% of silicon.
Quartz stone, we usually say that the quartz stone is a new type of stone artificially synthesized by more than 90% bai of quartz crystal plus resin and other trace elements. It is a large-size plate pressed by a special machine under certain physical and chemical conditions. Its main material is quartz.China quartz crucibles manufacturers
Quartz is a mineral that easily becomes liquid when heated or under pressure.

It is also a very common rock-forming mineral, which is found in the three major types of rocks. Because it is the latest to crystallize in igneous rocks, it usually lacks a complete crystal face and is mostly filled among other rock-forming minerals that crystallized first. The composition of quartz is the simplest silicon dioxide (Sio2), which is glassy, ​​has no cleavage surface, but has a shell-like fracture. Microcrystalline quartz is called chalcedony, agate or jasper. Pure quartz is colorless, but it shows a different color because it often contains impurities of transition elements. Quartz is very stable, not easy to weather or change into other kinds of minerals. According to the degree of crystallization of SiO2, it can be divided into crystalline single crystal quartz and polycrystalline quartzite jade.

Silica, chemical term, pure silica is colorless, solid at room temperature, chemical formula is SiO, insoluble in water. Insoluble in acid, but soluble in hydrofluoric acid and hot concentrated phosphoric acid, and can work with molten alkalis. There are two kinds of crystalline silica and amorphous silica in nature. Silica has a wide range of uses, mainly used to make glass, water glass, pottery, enamel, refractories, aerogel felt, ferrosilicon, molding sand, elemental silicon, cement, etc. In ancient times, silica was also used to make porcelain Glazed surface and carcass. General stones are mainly composed of silica and calcium carbonate.
