High-purity quartz is an irreplaceable mineral raw material for the manufacture of high-tech quartz glass and a rare and common high-value-added mineral resource required by strategic emerging industries.

 

Main application fields of high-purity quartz products

At present, with the development of a new generation of information and communication science and technology (ICT), such as cloud computing, big data, intelligent manufacturing and 5G technology, a new round of technological revolution and industrial transformation has been accelerated, and the development of strategic emerging industries is the solution. The key to today's industrial development in China. High-purity quartz is closely related to the new generation of information technology and new material industries in strategic emerging industries, and is an important supporting material in strategic emerging industries.

High-purity quartz is widely used in semiconductors, optical communications, photovoltaics, optics, electric light sources and other industries and fields. It is an important field supporting the development of strategic emerging industries, and an important guarantee for building major projects, improving people's livelihood, and consolidating national defense and military industries. It occupies an important position in the national economic construction.

 

1）Optical Fiber Communication

Optical fiber is an optical transmission tool. Quartz products are widely used in the optical fiber communication industry. Optical fiber communication has high anti-interference, high speed and large transmission capacity, and has become an important modern communication pillar. Plastic optical fibers and silica optical fibers are the two main types of optical fibers. However, the development of silica fiber is early, the technology is mature, and its excellent performance characteristics are widely used compared with plastic fiber.

 

2）Semiconductor Industry

The comprehensive strength of a country is reflected in the semiconductor industry, which is also known as the pearl of the national industry. Semiconductor components are widely used in communications, 3C, computers and other fields. The processing of ultra-clean studio wafers and quartz crucibles are applications of high-purity quartz products in the semiconductor industry.

 

3)Photovoltaic Industry 

One of the key raw materials in the photovoltaic industry is quartz, which is mainly used in quartz crucibles, quartz tubes and various quartz equipment. Both monocrystalline silicon and polycrystalline silicon in the photovoltaic industry are high-purity materials, which requires that the matching quartz materials must be high-purity materials. Generally, the photovoltaic industry requires quartz sand with a silica content greater than or equal to 99.99%, and the total content of impurity elements should be less than or equal to 25ug/g.

 

4)Optical Industry

Optical glass has stable optical properties and high optical uniformity. It is widely used in the fields of light transmission, light storage and optoelectronic display. It can be used to manufacture lenses, prisms, mirrors, windows, etc. . High-purity quartz sand plays a key role as the main raw material in the glass batch, accounting for 60%-80% of the glass batch. The quality of glass batches is not only related to the quality of optical glass products, but also affects the service life of glass melting furnaces. The use environment of optical glass products has very high requirements on impurity content, refractive index, light transmittance, and microscopic defects. , all these factors are very strict on the quality of the main raw material quartz sand.
