Quartz glass, as a high-performance industrial technical glass, has been widely used in many fields due to its unique physical and chemical properties.

Advantages of Quartz Glass

Excellent transparency: Quartz glass is usually colorless and transparent, with a visible light transmittance of over 85%, and some high-quality quartz glass can even achieve a visible light transmittance of over 95%. In the ultraviolet spectral region, the transmittance of quartz glass can also be maintained at over 80%, which makes it highly valuable in the field of optics.

Excellent high temperature resistance: The softening point temperature of quartz glass is about 1730 ℃, which can be used for a long time at 1100 ℃, and the short-term use temperature can reach 1450 ℃. This high temperature resistance enables quartz glass to maintain stable physical and chemical properties even in high-temperature environments.

Good thermal shock resistance: Quartz glass has a relatively small coefficient of thermal expansion, only one tenth to one twentieth of ordinary glass, thus possessing excellent thermal shock resistance. Even if quartz glass is heated to high temperature and quickly placed in room temperature water, it will not explode.

Strong corrosion resistance: Quartz glass has good resistance to acidic substances such as sulfuric acid, nitric acid, hydrochloric acid, aqua regia, and neutral salts. Except for hydrofluoric acid, its acid resistance is 30 times that of ceramics and 150 times that of stainless steel. This corrosion resistance makes quartz glass have a wide range of application prospects in the chemical industry.

Excellent electrical performance: Quartz glass has an extremely high resistance value, and its resistance at room temperature is ten or even ten thousand times that of ordinary glass, making it an excellent electrical insulation material. Even at high temperatures, quartz glass has good electrical properties.

Application of Quartz Glass

Semiconductor industry: Quartz glass is an indispensable material in the semiconductor industry. In the semiconductor production process, quartz glass products are mainly used in two stages: monocrystalline silicon manufacturing and wafer manufacturing. Various quartz components and instruments are materials required for cleaning, oxidation, photolithography, etching, diffusion, and other processes. The impurity content and geometric dimensions of quartz glass products directly affect the yield and production efficiency of integrated circuit devices.

Aerospace industry: Quartz glass fiber and composite materials based on quartz glass fiber have excellent high temperature resistance, erosion resistance, high transparency, and electrical insulation properties, and are widely used as functional materials in the fields of aerospace and marine equipment.

Optics industry: Synthetic quartz glass materials are used as lenses, prisms, and photomask substrates for TFT-LCD high-definition displays and ICs in the high-end optical field. With the rapid development of the optical instrumentation industry, the application prospects of quartz glass in the optical field are becoming increasingly broad.

Optical communication industry: The application of quartz glass in the field of optical communication is mainly reflected in the manufacturing of optical fibers. More than 95% of the components in fiber preform rods are high-purity quartz glass, and a large amount of quartz glass material is required in fiber production processes such as rod making and drawing, such as holding rods and quartz cups. With the acceleration of new information infrastructure construction such as 5G and gigabit optical networks, the rapid development of the optical communication industry will drive the continuous increase in demand for quartz glass.

In addition, quartz glass has a wide range of applications in fields such as photovoltaics and electric light sources. In the field of photovoltaics, high-purity quartz sand is the main raw material for producing quartz crucibles for monocrystalline silicon photovoltaics. With the further expansion of crystal pulling and cell manufacturing processes, its market demand will show a strong trend. In the field of electric light sources, quartz glass is widely used in the manufacturing of various electric light source products due to its excellent transparency and high temperature resistance.

Quartz glass has broad application prospects in various fields such as semiconductors, aerospace, optics, and optical communication due to its unique physical and chemical properties.
