Wholesale Custom High-Purity Quartz Furnace Tube for Laboratory & Industrial Use - China Suppliers & Factory Factory, Products

Quartz furnace tubes, manufactured from high-purity quartz sand, offer exceptional resistance to high temperatures, capable of withstanding up to 1200℃ or more. Renowned for their excellent thermal stability and strong chemical inertness, these tubes are integral components in high-temperature heat treatment processes across various industries, including semiconductors, photovoltaics, and new materials. They play a crucial role in vacuum and diffusion furnaces, These quartz furnace tubes serve as essential components in thermal processing equipment used for semiconductor and photovoltaic applications. Constructed from high-purity silicon dioxide (SiO₂), they function as the reaction chamber within high-temperature diffusion and oxidation furnaces, providing a controlled environment for wafer processing at elevated temperatures, Our quartz furnace tubes are made from high-purity synthetic fused silica (SiO₂ ≥99.99%) with a low hydroxyl (OH) content of less than 50ppm. As a leading factory and supplier in China, we ensure the highest quality products to meet the demands of advanced industrial applications

❓ Frequently Asked Questions
Q. What shapes are available for the quartz tubes?
We offer straight tubes, U-shaped tubes, spiral tubes, and fully customized special structures to meet specific application requirements.
Q. What size range do your quartz tubes cover?
Our quartz tubes are available with an outer diameter from 10mm to 500mm, wall thickness from 1mm to 20mm, and lengths from 100mm to 6000mm. Custom dimensions are also accepted based on customer drawings.
Q. Can quartz tubes be made with vacuum-sealed or closed-end designs?
Yes. We support flange connection, closed-end, quartz flange, and vacuum-sealed designs to accommodate various industrial and laboratory needs.
Q. What surface treatment options are available?
We provide polished surfaces (both inner and outer), frosted finishes, and acid-etched surfaces, depending on the optical, chemical, or mechanical requirements of your application.
Q. Can I order quartz tubes based on my own drawings or specifications?
Absolutely. All dimensions and structural configurations can be customized per customer drawings. Please provide your technical drawings or detailed specifications when placing an inquiry.
Q. What is the difference between frosted and acid-etched quartz tube surfaces?
Frosted surfaces are mechanically processed to create a uniform matte finish, while acid-etched surfaces are chemically treated to achieve a more refined texture with improved optical diffusion properties. The choice depends on your specific use case.
