As a high-performance specialty glass, quartz glass excels in high-temperature environments due to its unique physical and chemical properties.

Basic Composition and Properties of Quartz Glass.

Quartz glass is mainly composed of silicon dioxide (SiO2), a very stable compound with extremely high chemical and thermal stability. Quartz glass has a high melt temperature viscosity, which allows it to maintain a good form and structure at high temperatures. In addition, quartz glass exhibits excellent light transmission, electrical insulation and chemical stability.

Mechanism of high temperature resistance of quartz glass

The high temperature resistance of quartz glass is mainly due to its stable chemical composition and special production process. Silicon dioxide is not easy to react with other substances at high temperatures, so quartz glass has excellent corrosion and oxidation resistance. In order to improve the high temperature resistance of quartz glass, you can also add alumina (Al2O3), magnesium oxide (MgO), potassium oxide (K2O) and other oxides, these oxides at high temperatures can form a stable silicate with silica, thus improving the high temperature resistance of quartz glass.

In addition, by changing the production process, such as controlling the cooling rate of molten quartz glass to form a microcrystalline structure, can also further improve its high temperature resistance. Doping other elements, such as zirconium (ZrO2), titanium (TiO2), etc., can also enhance the high temperature resistance of quartz glass.

Temperature range of quartz glass

The high temperature resistance of quartz glass is outstanding, and its softening point temperature is about 1730℃. Under normal use conditions, quartz glass can be used for a long time at 1100℃, and the maximum use temperature for a short time can reach 1450℃. This high temperature resistance makes the application of quartz glass in high temperature environment possible.

Application of quartz glass in high temperature environment

Quartz glass is widely used in many fields due to its excellent high temperature resistance. For example, in laboratory equipment and refining equipment for special high-purity products, quartz glass is favored for its high purity and high-temperature resistance. In addition, quartz glass is widely used in semiconductors, electric light sources, semi-conducting communication devices, lasers, optical instruments, and other fields.

The protective role of quartz glass is crucial during high-temperature chemical reactions, physical measurements, and other processes. Its stable chemical properties and high-temperature resistance enable it to maintain stable performance under extreme conditions, thus ensuring the smooth running of experiments or production.

Other properties of quartz glass

In addition to its high-temperature resistance, quartz glass has a variety of other excellent properties. For example, its coefficient of thermal expansion is so small that it can withstand drastic temperature changes, and quartz glass will not explode when heated to about 1100°C and placed in room temperature water. In addition, quartz glass in the ultraviolet to infrared light throughout the spectral band have good light transmission properties, visible light transmission rate of more than 93%, especially in the ultraviolet spectral region, the maximum transmittance rate of up to 80% or more. At the same time, the resistance value of quartz glass is equivalent to 10,000 times that of ordinary glass, which is an excellent electrical insulating material, even at high temperatures also has good electrical properties.

Quartz glass excels in high-temperature environments due to its stable chemical composition, special production process, and excellent high-temperature resistance. Its wide range of applications and many excellent properties make quartz glass an indispensable high-performance material.
