Quartz glass withstands continuous operating temperatures of 1100°C to 1200°C, with short-term exposure possible up to 1400°C depending on grade and geometry. The absolute softening point is far higher—typically quoted between 1500°C and 1670°C—but no responsible supplier recommends operating near t

What is a quartz sleeve, and why does selection matter?Quartz sleeve is a high-purity fused silica tube used to protect UV lamps, isolate process environments, or serve as a structural support component in high-temperature equipment. Selection matters because an incorrectly specified sleeve—wrong OD

Selecting the right quartz ring depends on three factors: purity grade (4N for industrial, 5N–6N for semiconductor/optical), dimensional tolerance (standard ±0.1 mm vs. precision ±0.01 mm), and operating temperature (up to 1200°C continuous). For non-standard sizes, tight deadlines, or small-batch r
