Accurately distinguishing between quartz tubes and ordinary glass tubes is the key to ensuring experimental safety and production yield in the fields of industry and scientific research. Although the appearance of the two is similar, the core difference lies in the purity of silicon dioxide: the pur

The long-term continuous use temperature of quartz tubes is usually recommended to be controlled within 1100 ℃, and the short-term ultimate temperature resistance can reach 1450 ℃. If operated at high temperatures exceeding 1100 ℃ for a long time, quartz tubes will indeed face softening deformation

Under high temperature applications, the thermal expansion coefficient of quartz glass is extremely low, usually between 0.5 × 10 ⁻⁶/℃ and 0.55 × 10 ⁻⁶/℃. This characteristic enables it to maintain excellent dimensional stability and almost no deformation even when subjected to drastic temperature c
