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, making it highly suitable for high-temperature industrial and laboratory applications.
The extremely low thermal expansion coefficient (5.5 × 10⁻⁷ cm/cm·°C) is a result of its high silicon dioxide purity and amorphous molecular structure, which minimizes dimensional changes under temperature fluctuations and provides exceptional thermal shock resistance.
The quartz glass is available in controlled purity grades of 10 PPM, 20 PPM, and 100 PPM, allowing customers to select the appropriate level of trace element content for semiconductor, optical, or general industrial use.
The circular fused quartz glass discs are available in thicknesses ranging from 2 MM to 20 MM, providing flexibility for a wide variety of engineering and optical applications.
Yes. The quartz glass is manufactured to strict surface quality standards — completely free of air bubbles and surface lines — ensuring optical clarity and structural integrity for precision applications.
The compressive strength of this fused quartz glass is 1100 MPa, which is significantly higher than standard borosilicate glass and many ceramics, making it an excellent choice for applications requiring both mechanical durability and high-temperature performance.
