Quartz glass is an inorganic non-metallic material and is a special industrial glass composed of a single component of silicon dioxide (SiO2). Quartz glass has excellent performance, high temperature resistance, high hardness, small expansion coefficient, high spectral transmittance, stable chemical properties, and excellent electrical insulation. It can be processed into quartz crucibles, quartz tubes, quartz fibers and other products, and is widely used in semiconductors, Instrumentation, optical fiber, aerospace, optical communication, photovoltaics and other fields, among which semiconductor is the main application field of quartz glass, accounting for more than 60% of the application.
According to the "2023-2027 China Quartz Glass Industry Market Monitoring and Future Development Prospect Research Report" released by the Xinsijie Industry Research Center, benefiting from the country's support for semiconductor, optical fiber and other industries, the demand for quartz glass applications continues to release. In 2021 In 2018, the scale of my country's quartz glass market reached 8.86 billion yuan, accounting for about 35.8% of the global market. It is estimated that from 2023 to 2027, the scale of my country's quartz glass market will maintain a low-speed growth trend, and the average annual compound growth rate will be around 0.6%.
The preparation process of quartz glass is divided into electric melting method, gas refining method and chemical synthesis method. In terms of classification, according to different purity, quartz glass can be divided into high-purity quartz glass, doped quartz glass, and ordinary quartz glass; according to different transparency, quartz glass can be divided into two categories: transparent quartz glass and opaque quartz glass; according to different functions , Quartz glass is divided into low-expansion quartz glass, radiation-resistant quartz glass, ultraviolet filter quartz glass, etc.
Quartz glass is widely used in the semiconductor field, almost running through every link of the semiconductor industry chain, including semiconductor process diffusion, deposition, etching, etc. my country is the world's largest semiconductor market, with sales reaching more than US$190 million in 2021. During the "14th Five-Year Plan" period, with the support of national policies, my country's semiconductor industry will continue to expand, thereby providing a broader development space for the quartz glass market.
The upstream of the quartz glass industry chain is the supply layer of quartz sand. The main players in the world include Unimin, Norway TQC, Quartz Co., Ltd., etc.; the middle reaches of the industrial chain is the production layer of quartz glass and its products. Tosoh, Heraeus of Germany, Philips Stone, Shanghai Qianghua, Shenyang Hanke, etc. Due to the high requirements for production technology and equipment of quartz glass products, there is still a certain gap between domestic production enterprises and foreign enterprises.
Industry analysts from Xinsijie said that quartz glass has excellent performance and can be used in a wide range of fields, among which semiconductors are the most important application scenario. Benefiting from the development of the semiconductor industry, the quartz glass market space continues to expand, and the industry has a good development prospect. There are many types of quartz glass and various related products. In the future, with the advancement of technology and the upgrading of downstream demand, the quartz glass market will continue to develop in the direction of high purification and high-end.
