For high-temperature applications exceeding 500°C, quartz tubes (fused silica) are significantly better than standard glass tubes. Quartz tubes withstand continuous operating temperatures up to 1100°C and short-term exposure to 1450°C, while borosilicate glass tubes typically soften around 820°C and

Quartz tubes are used wherever extreme heat, chemical exposure, UV transmission, or dimensional precision makes ordinary materials unsuitable. The five industries that rely on quartz tubes most heavily are semiconductor manufacturing, high-temperature furnace engineering, optical and UV equipment, c

Quartz tubes can withstand up to 1100°C for continuous operation and up to 1200°C for short-term use (typically less than 3 hours). The softening point — where deformation begins — is approximately 1650°C, but this is a failure limit, not a working temperature. The true performance limit is determin
