Custom Custom High-Purity Quartz Furnace Tubes from China Suppliers and Factory for Laboratory and Industrial Use Manufacturer, Supplier

Quartz furnace tubes, produced by leading suppliers in China, are crafted from high-purity quartz sand, offering exceptional resistance to extreme temperatures (up to 1200℃ or higher). These tubes boast excellent thermal stability and remarkable chemical inertness, making them suitable for high-temperature heat treatment applications. They are essential components in vacuum furnaces and diffusion furnaces, widely used in the semiconductor, photovoltaic, and advanced materials fields, As a crucial element in thermal processing equipment for semiconductors and photovoltaics, our quartz furnace tubes are made from high-purity silicon dioxide (SiO₂) and serve as the reaction chamber in high-temperature furnaces like diffusion and oxidation furnaces. They ensure a controlled environment for wafer processing under elevated temperatures, Material: High-purity synthetic fused silica (SiO₂ ≥99.99%), with low hydroxyl (OH) content (

Frequently Asked Questions
Q: What tube shapes are available?
A: We offer straight tubes, U-shaped tubes, spiral tubes, and fully customized special structures to meet various industrial and laboratory requirements.
Q: What are the available size ranges for the tubes?
A: The outer diameter ranges from 10mm to 500mm, wall thickness from 1mm to 20mm, and length from 100mm to 6000mm. All dimensions can be manufactured according to customer drawings.
Q: Is a vacuum-sealed design available?
A: Yes. We support vacuum-sealed designs along with flange connection, closed end, and quartz flange options, making the tubes suitable for high-precision and vacuum environments.
Q: What surface treatment options are offered?
A: Surface treatment options include polished (inner and/or outer surface), frosted, and acid-etched finishes. Each treatment serves different optical, chemical, and mechanical purposes.
Q: Can tubes be manufactured to custom specifications?
A: Absolutely. All products can be customized based on customer-supplied drawings, including special shapes, specific dimensions, connection types, and surface finishes.
Q: What is the difference between polished and acid-etched surface treatments?
A: Polished surfaces provide a smooth, transparent finish ideal for optical applications, while acid-etched surfaces create a matte, diffused appearance commonly used for UV or light-diffusing purposes.
