Quartz is resistant to corrosion, high temperature, radiation, low coefficient of expansion, and outstanding insulation performance. The chemical formula of quartz is SiO2. Pure quartz is colorless and transparent. It contains a variety of colors due to trace pigment ions or finely dispersed inclusions, or the presence of a color center, and reduces the transparency. With glass luster, it is one of the most widely distributed minerals on the earth's surface.
Quartz has unique optical, mechanical, and thermal properties, including:
(1) High softening temperature and strong heat resistance;
(2) High purity and corrosion resistance;
(3) Low thermal expansion coefficient and thermal shock resistance;
(4) It has good light transmission performance from ultraviolet to infrared;
(5) Strong radiation resistance;
(6) Excellent electrical insulation.
The above properties make quartz products widely used in high-end manufacturing fields such as aerospace, nuclear laser, semiconductor, optical communication, metallurgy, chemical industry, and electric light source.
Application
High-performance quartz stone has key applications in high-end fields such as electronic information and aerospace.
High-performance quartz materials are indispensable and important basic materials for electronic information, optical light sources, photovoltaic energy, aerospace and other industries. They play a key role in major national projects and aerospace, electronic information and other industries. Quartz is used as the standard frequency material.
From the perspective of the industrial chain, quartz sand is made into quartz tubes, quartz rods, quartz crucibles and other quartz products through processes such as gas melting and electric melting. It is mainly used in semiconductors, electric light sources, photovoltaics, aerospace and other fields.
