Our quartz glass products have a softening point of 1680°C and can withstand continuous operating temperatures up to 1200°C. The material exhibits exceptional thermal shock resistance, allowing rapid temperature changes from 1100°C to room temperature without cracking or structural damage. The annealing point is 1215°C and strain point is 1120°C. For short-term exposure, quartz glass can handle temperatures up to 1300°C. The low thermal expansion coefficient (0.5 × 10⁻⁶/K) contributes to superior thermal shock resistance compared to other glass materials. This makes our quartz glass ideal for high-temperature furnaces, rapid thermal processing equipment, and applications involving extreme temperature cycling.
