Quartz glass - the "crown" of glass material

Quartz is one of the most abundant minerals in nature. Its chemical composition is SiO2. It has many variants under different temperature conditions: below 573 °C, it is called α quartz, which has piezoelectric effect; above 573 °C, it is called It is beta quartz. Among them, pure, crystallized and transparent α-quartz is also called crystal. It is a crystal with a fixed crystal shape. It has been favored by human beings since ancient times, and it is included in the ranks of gemstones all over the world.

Quartz glass is also composed of a single SiO2, but it is a glass formed by melting or chemical reaction of quartz powder. It has the characteristics of "long-range disorder, short-range order", which is amorphous, and the purity of SiO2 can reach 99.9999%.

Compared with ordinary glass, quartz glass has superior physical and chemical properties, and it is widely used as an important material in high-end equipment in the fields of national economy, national special projects and defense industry.

The quartz sight glass and lens used in spacecraft and space camera can change color without generating "color center" under the irradiation of cosmic ray particles, ensuring the accuracy and effectiveness of surveying and mapping; wafer diffusion, oxidation, deposition, annealing treatment In the process, the support frame is the only material that directly contacts the silicon solution, which plays the most important role in the quality and yield of single crystal silicon. High-purity quartz glass is the only material that can be used during the pickling process of quartz. The glass flower basket and quartz glass cleaning tank can be corroded, acid and alkali resistant; the purity, high temperature deformation resistance, geometric size and appearance quality of the diffusion tube in the integrated circuit directly determine the quality, cost and production efficiency of the final integrated circuit and device. A large number of comprehensive tests, only quartz glass meets all requirements; the microscopic internal quality of the photomask substrate determines the accuracy of the scribe line, the high UV transmittance of high quality quartz glass and the extremely high internal uniformity ensure the accuracy and accuracy of the work. degree.

The high mechanical strength, good chemical stability, wide spectral transmission, thermal shock resistance, high temperature deformation resistance, radiation resistance and electrical insulation make the quartz glass the crown of the glass material.
