High-Purity Quartz Glass Low Pressure Diffusion Furnace Tubes – Southeast Quartz China Manufacturer
Product Introduction
Our Quartz Glass Low Pressure Diffusion Furnace Tubes are crafted from ultra-high purity fused silica, with a SiO₂ content exceeding 99.99%, ensuring superior optical clarity, excellent mechanical strength, and outstanding thermal stability. Manufactured by Southeast Quartz China, these tubes are specifically engineered for low pressure diffusion processes used in semiconductor fabrication, photovoltaic production, and advanced laboratory applications.
With their smooth, polished inner surface, our furnace tubes minimize particle contamination, allowing precise control of thermal and chemical environments during diffusion, oxidation, or annealing processes. They exhibit exceptional transmittance in ultraviolet, visible, and infrared light ranges, making them suitable for both high-temperature heating and optical-based monitoring systems.
