Fused quartz glass can withstand a short-term use temperature of up to 1300 °C and a long-term use temperature of up to 1100 °C. Its softening point is as high as 1780 °C, making it suitable for extreme high-temperature environments.
Fused quartz glass is made from high-purity Silicon Dioxide (Natural Quartz), which gives it an exceptionally low thermal expansion coefficient of 5.5 × 10⁻⁷ cm/cm·°C. This property allows it to resist thermal shock and maintain dimensional stability across a wide temperature range.
Fused quartz glass is available in thicknesses ranging from 2 mm to 20 mm, providing flexibility for a wide variety of industrial and optical applications.
The fused quartz glass is available in controlled purity grades of 10 PPM, 20 PPM, and 100 PPM, allowing customers to select the appropriate level of purity for their specific application requirements, including semiconductor and high-precision optical uses.
Fused quartz glass has a compressive strength of 1100 MPa, which is significantly higher than standard soda-lime glass. Combined with a Young's Modulus of 72,000 MPa, it exhibits excellent rigidity and resistance to compressive forces in demanding applications.
Yes. The fused quartz glass is manufactured to be free of air bubbles and surface lines, ensuring optical clarity and structural integrity. Its transparent or colorless appearance and high index of refraction (1.4585) make it ideal for optical and precision applications.
