Why do quartz tube glass products remain durable over time?

Quartz glass tubing exhibits excellent low-temperature resistance and is widely used in second- and third-generation advanced lighting sources. Annual consumption of quartz glass amounts to 2,000 tons, supporting the production of 300 million halogen tungsten lamps and 15 million mercury lamps; it is also employed in the manufacture of xenon lamps, pulsed lamps, atomic‑spectroscopy lamps, and other indispensable light sources for modern technology. Composed of pure silicon dioxide, quartz glass is an essential high-purity material in the electronics industry; crucibles for growing silicon single crystals, diffusion tubes used in integrated circuit fabrication, and various laboratory vessels are all made from quartz glass.
