Why Quartz Glass? The Material That Makes Light-Driven Reactions Shine

At the heart of every high-performance photoreactor lies its reaction chamber, and quartz glass stands unrivaled for this critical role. Unlike ordinary glass, which absorbs most ultraviolet (UV) light below 300 nm, quartz glass boasts over 90% transmittance from deep UV (~185 nm) to near-infrared wavelengths 2. This is a game-changer for photocatalysis, as key catalysts like titanium dioxide (TiO₂) require UV light (around 385 nm) to activate—quartz ensures every photon counts, drastically boosting reaction efficiency.

Quartz’s advantages extend far beyond optical clarity. Its ultra-low thermal expansion coefficient allows it to withstand extreme temperature swings (from rapid cooling to sustained use at 1100–1250℃) without cracking, a vital feature given the heat generated by high-power light sources 2. Additionally, its exceptional chemical inertness—resisting all acids except hydrofluoric acid and most organic solvents—makes it ideal for harsh reaction environments, outperforming ceramics by 30 times and stainless steel by 150 times in acid resistance 2. For sensitive processes like pharmaceutical synthesis, its high purity eliminates metal contamination, ensuring consistent, reproducible results.
