Quartz furnace tubes are made from high-purity quartz sand. They are resistant to high temperatures (up to 1200℃ or higher), have good thermal stability and strong chemical inertness. They are widely used in high-temperature heat treatment in fields such as semiconductors, photovoltaics, and new materials, and are the core components of vacuum furnaces and custom size quartz furnace tube for laboratory and industrial use diffusion furnaces.
A quartz furnace tube is a key component used in semiconductor and photovoltaic thermal processing equipment. It is made from high-purity silicon dioxide (SiO₂) and serves as the reaction chamber inside high-temperature furnaces such as diffusion and oxidation furnaces.
It provides a controlled environment for wafer processing at elevated temperatures.
Material: High-purity synthetic fused silica (SiO₂ ≥99.99%), low hydroxyl (OH) content (<50ppm)
