Quartz glass properties

  1. Excellent heat resistance: Quartz glass has a softening point temperature of approximately 1730°C, which allows it to be used for long periods of time in environments up to 1100°C, and can even withstand temperatures as high as 1450°C for short periods of time. This outstanding high temperature resistance makes quartz glass uniquely suited to application scenarios where extreme temperatures need to be withstood.
  2. Strong chemical stability: quartz glass is extremely resistant to corrosion, and it reacts with virtually no acids other than hydrofluoric acid. Its acid corrosion resistance far exceeds that of acid-resistant ceramics and stainless steel, especially in high-temperature environments, where this chemical stability is particularly prominent. This makes quartz glass in the chemical, pharmaceutical and other industries that need to resist the erosion of chemical substances have a wide range of applications.
  3. Outstanding Thermal Stability: Quartz glass has an extremely low coefficient of thermal expansion, which means it can withstand drastic temperature changes without breaking or deforming easily. Even when heated to approximately 1100°C and then quickly placed in room temperature water, quartz glass will not burst, a characteristic that makes it stable at high temperatures and in alternating hot and cold environments.
  4. Excellent optical properties: quartz glass has good light transmission properties in the entire spectral band from ultraviolet to infrared, which makes it widely used in the field of optoelectronics. Whether it is used as a basic material for optical instruments or for manufacturing windows and lenses with high light transmission, quartz glass can bring its unique advantages into play.
  5. Excellent electrical insulation performance: quartz glass has an extremely high resistance value, equivalent to 10,000 times that of ordinary glass, which makes it an excellent electrical insulation material. Even at high temperatures, quartz glass maintains good electrical properties, so it has a wide range of applications in the power and electronics industries.
