The purity grade of quartz glass you should choose depends almost entirely on how sensitive your process is to trace contamination. For general industrial furnace tubes and chemical apparatus, fused quartz with 99.9%–99.99% SiO₂ and total metallic impurities below roughly 20–50 ppm is usually suffic

Is Quartz Transparent to UV Light? UV Transmission and ApplicationsYes, quartz glass is highly transparent to ultraviolet (UV) light—but the degree of transparency depends heavily on the grade of quartz you choose. Standard fused quartz transmits well across most of the UV spectrum, while UV-grade s

Is Quartz Resistant to ChemicalsYes, quartz is highly resistant to most chemicals—but not all of them. Fused quartz glass withstands attack from virtually all acids (except hydrofluoric acid and hot phosphoric acid above 300°C), is largely inert to water and salt solutions, and outperforms most meta
