Square quartz glass tube is a special glass product made of high-purity fused silica. With its unique geometric shape and inherent excellent performance of quartz material, it plays an irreplaceable role in semiconductor, photovoltaic, optics, chemical industry and other fields.
Product core advantage: Why choose square quartz glass tube?
Square quartz glass tube not only inherits all the advantages of fused silica material, but also solves many application limitations of circular tube through its square structure.
1. Excellent thermal stability
Extremely low coefficient of thermal expansion: The coefficient of thermal expansion is as low as about 5.5 x 10 ⁻⁷/K, which can withstand severe temperature fluctuations (thermal shock) without cracking, and the working temperature can reach up to 1100 ℃.
High temperature resistance: It can maintain stability in shape and strength even when working in high temperature environments for a long time, without the risk of crystallization.
2. Excellent optical performance
High transmittance: It has extremely high transmittance in the broad spectral range from ultraviolet to infrared (especially in the ultraviolet band, far exceeding ordinary glass), making it an ideal choice for ultraviolet lamps and optical windows.
Optical uniformity: There are no bubbles or stripes inside, ensuring distortion free light transmission and guaranteeing the accuracy of the optical system.
3. Accurate geometric structure and mechanical performance
Flat surface: Multiple square surfaces facilitate seamless integration and sealing with other components such as sensors, light sources, and seals, simplifying system integration.
Structural stability: Compared to circular pipes, square pipes are more stable during stacking, fixing, and installation, and are less prone to rolling, making it easier to achieve a compact and stable layout in equipment.
High purity and chemical inertness: With a SiO ₂ content of over 99.99%, it is resistant to strong acids and alkalis (except hydrofluoric acid and hot phosphoric acid), ensuring the purity of the process and avoiding pollution.
Main application areas
Square quartz glass tubes, with their comprehensive performance, have become the core components in the following high-tech fields:
Semiconductor and integrated circuit manufacturing: used as furnace tubes for diffusion tubes, oxidation tubes, and CVD (chemical vapor deposition) reaction chambers. Its high purity and high temperature resistance are the key to ensuring a pure chip manufacturing environment.
Photovoltaic industry: As a guide rail and furnace tube for carrying quartz boats in the sintering and annealing processes of solar cells, the dimensional stability at high temperatures is crucial.
Optoelectronics and Lighting: As the casing of high-power ultraviolet lamps, halogen lamps, and sterilization lamps, its excellent ultraviolet transmittance can maximize light efficiency.
Precision chemical and analytical instruments: used for making observation windows, reaction vessel liners, sample tanks, which can withstand corrosive media and provide clear observation views under high temperature and high pressure.
Research and experimental equipment: In customized experimental equipment, it serves as a reaction chamber, vacuum chamber, or optical path to meet specific research needs.
Customer pain points that we can solve
Square quartz glass tubes directly address and solve key issues in the application of circular quartz tubes or other material fittings:
Solving the problem of "unstable installation": replacing circular pipes, eliminating problems such as inaccurate positioning and difficult fixation caused by rolling during equipment installation.
Solving the problem of low space utilization: Square cross-sections are easier to arrange tightly inside equipment, achieving higher space utilization efficiency, especially suitable for multi tube parallel heating systems.
Solving the problem of "difficult interface sealing and coupling": A flat surface makes sealing and docking with flat flanges, cover plates, or optical components more convenient and reliable, reducing the complexity of system design.
Addressing the issue of pollution and deformation at high temperatures: Compared to metal or ordinary glass, quartz glass does not release pollutants or deform at high temperatures, ensuring the purity and repeatability of high-temperature processes.
