Custom Size Quartz Furnace Tube for Laboratory & Industrial Use - High-Purity from China Suppliers & Factory

Quartz furnace tubes are essential components manufactured from high-purity quartz sand, known for their exceptional resistance to high temperatures exceeding 1200℃. These tubes demonstrate excellent thermal stability and strong chemical inertness, making them ideal for high-temperature heat treatments across various industries, including semiconductors, photovoltaics, and advanced materials. As vital parts of vacuum furnaces and diffusion furnaces, quartz furnace tubes play a crucial role in thermal processing equipment, In high-temperature applications, these quartz furnace tubes, crafted from high-purity silicon dioxide (SiO₂), serve as the reaction chamber in diffusion and oxidation furnaces, providing an optimal controlled environment for wafer processing at elevated temperatures, Our quartz furnace tubes are made from high-purity synthetic fused silica (SiO₂ ≥99.99%) with low hydroxyl (OH) content (
