Uses of Natural Crystals
According to the appearance and physical characteristics of the crystal, it is divided into four categories: pressure crystal, optical crystal, craft crystal and smelting crystal. According to the use, it can be divided into crystal for crafts and crystal for industrial use.
Industrial crystal stone utilizes the physical properties of crystal, chemical properties and high purity of silica. As a raw material, quartz glass and industrial devices are produced. Pressure crystal, optical crystal, and smelting crystal are industrial crystals.
Quartz glass made of crystal high-purity silica, with good color temperature resistance, acid resistance, alkali resistance, small linear expansion coefficient, etc., can produce a variety of quartz glassware, quartz glass tube, quartz glass rod, widely used in the defense industry, semiconductor industry, optical industry, electric light source, metallurgy, chemical and other industries.
