High-Purity Quartz Tubes Become Core Component of Vacuum Furnaces-Amy
2026/07/10
High-purity fused quartz tubes have emerged as the preferred chamber material for lab and industrial vacuum furnaces.
Made of 99.99% silica, they withstand continuous high temperature up to 1600°C with outstanding thermal shock resistance. Fully stress-relief annealed tubes maintain stable air tightness under high vacuum, free from cracking during repeated heating and cooling cycles.
Chemically inert to acids, alkalis and process gases, quartz avoids contamination of semiconductor, battery and ceramic samples. Its transparent body allows real-time visual observation of sintering and annealing processes.
Custom sizes, flanged ends and special processing are available to match diffusion furnaces, CVD equipment and material research vacuum tube furnaces. Domestic quartz tubes deliver equivalent performance to imported products with shorter lead time and lower cost, supporting advanced thermal processing sectors.
