High-Quality Custom Size Quartz Furnace Tube for Laboratory & Industrial Use | China Suppliers & Factory Suppliers, Products

Quartz furnace tubes are essential components crafted from high-purity quartz sand, known for their exceptional resistance to elevated temperatures (up to 1200℃ or higher). These tubes exhibit excellent thermal stability and robust chemical inertness, making them indispensable in high-temperature heat treatment processes across industries such as semiconductors, photovoltaics, and new materials. They play a crucial role in vacuum furnaces and diffusion furnaces, Manufactured from high-purity silicon dioxide (SiO₂), our quartz furnace tubes serve as the reaction chamber in advanced thermal processing equipment, including diffusion and oxidation furnaces. They ensure a controlled environment for wafer processing at high temperatures, optimizing performance and efficiency, Material: High-purity synthetic fused silica (SiO₂ ≥99.99%), with low hydroxyl (OH) content (

Frequently Asked Questions

Q What shapes are available for the quartz tubes?
The quartz tubes are available in straight tube, U-shaped tube, and spiral tube configurations. Custom special structures can also be manufactured according to specific application requirements.
Q What size range do the quartz tubes cover?
The tubes are offered with an outer diameter ranging from 10mm to 500mm, a wall thickness of 1mm to 20mm, and a length of 100mm to 6000mm. Dimensions can be tailored to match customer-supplied drawings.
Q Can the tubes be manufactured with a vacuum-sealed design?
Yes. Vacuum-sealed designs are available as a standard feature option, along with flange connections, closed ends, and quartz flanges, making them suitable for high-vacuum and controlled-atmosphere applications.
Q What surface treatment options are offered?
Three surface treatment options are available: polished (on inner surface, outer surface, or both), frosted, and acid-etched. Each finish serves different optical, cleanliness, and functional requirements.
Q Is it possible to order custom-shaped quartz tubes?
Absolutely. In addition to standard shapes, customized special structures can be produced based on customer-provided drawings or specifications, allowing full flexibility for unique industrial or laboratory needs.
Q What connection methods are supported for the quartz tubes?
The tubes support flange connection and quartz flange options, as well as closed-end designs. These connection features ensure compatibility with a wide range of equipment setups and integration requirements.
