U-shaped transparent quartz glass tube
U-shaped transparent quartz glass tubes are special glass products made by precisely processing high-purity natural quartz sand or synthetic silicon sources after high-temperature melting. Its unique U-shaped integrated structure, combined with the outstanding physical and chemical properties of quartz glass, provides a reliable solution for light transmission, peeping, reaction and flow guidance applications in harsh environments. This product, with its outstanding thermal stability, optical transmittance and chemical inertness, has become an indispensable basic material in the fields of semiconductors, optoelectronics, chemical engineering and scientific research.
Core advantages and product features
1. Ultimate thermal stability
High-temperature resistance: The softening point is as high as 1730℃, the long-term service temperature can reach 1200℃, and the short-term service temperature can reach 1450℃, without significant performance degradation.
Extremely low coefficient of thermal expansion: The coefficient of thermal expansion is only 5.5 x 10⁻⁷ /K, approximately 1/15 of that of ordinary glass, ensuring dimensional stability under rapid temperature changes.
Outstanding thermal shock resistance: It can withstand a sharp temperature difference from 1000℃ when directly immersed in room-temperature water without cracking, far exceeding any other type of industrial glass.
2. Excellent optical performance
High transmittance: It has high transmittance across a wide spectral range from ultraviolet, visible to near-infrared (for example, it still has good transmittance in the deep ultraviolet band of 185nm), making it an ideal choice for ultraviolet lamps, optical Windows and spectral instruments.
Optical uniformity: The material is pure, free of bubbles and stripes, ensuring no distortion in light transmission and clear imaging.
3. Excellent chemical inertness and physical strength
High chemical purity and corrosion resistance: It hardly reacts with other acid substances except hydrofluoric acid and hot phosphoric acid. It also has a certain resistance to alkalis. High-purity materials ensure that no metal ion contamination is introduced in the semiconductor process.
High mechanical strength: Compared with ordinary glass, it has higher compressive strength and flexural strength, a more stable structure, and a longer service life.
4. Precise geometric consistency
By adopting advanced CNC hot processing technology, the roundness of the U-shaped elbow section, the uniformity of wall thickness and the parallelism of the two arms are ensured, meeting the requirements of high-precision assembly.
Main application fields
U-shaped quartz glass tubes, with their comprehensive performance, play a core role in the following key areas
Semiconductor and photovoltaic industry
Diffusion and oxidation process: As a wafer carrier, it conveys silicon wafers in a high-temperature diffusion furnace.
LED packaging: Used as a bracket or packaging shell for high-power leds, it features high light transmittance and insulation.
Photovoltaic cell manufacturing: Chamber components for thin-film deposition equipment such as PECVD.
Optoelectronics and lighting industry
Ultraviolet light source: The core material for manufacturing sterilization lamps, exposure machines, and ultraviolet lamp tubes used in spectral analysis.
Halogen lamps and xenon lamps: As the outer bulb shells of high-intensity gas discharge lamps, they can withstand high temperatures and high pressures.
Chemical Engineering and Environmental Protection Engineering
Corrosion-resistant sight glass: Installed on reaction vessels and pipelines, it is used to observe the reaction conditions inside highly corrosive media.
Analytical instrument: As the sampling tube and measurement cell of the continuous emission monitoring system (CEMS) for flue gas, it can withstand high temperatures and highly corrosive waste gas.
Scientific Research and Laboratory
Customized reactors: used in experimental devices such as photochemical reactions, high-temperature synthesis, and vacuum systems.
Precision instrument components: As optical elements or structural parts in equipment such as spectrometers, telescopes, and lasers.
The key problems we can solve
1.Solve the problem of device failure caused by high temperature and thermal shock: Replace ordinary glass or metal tubes, and in the process of rapid temperature rise and fall, avoid production interruption and safety risks caused by material cracking or deformation.
2. Addressing chemical corrosion and pollution issues: In environments involving strong acids, strong alkalis or high-purity chemicals, provide long-term stable services to prevent containers from being corroded and products from being contaminated.
3. Solving the bottleneck of ultraviolet light transmission and application: Providing an efficient light transmission channel for deep ultraviolet band applications (such as sterilization, curing, and analysis), and making up for the defect that ordinary glass does not transmit ultraviolet light.
4. Solve the problem of blurred and vulnerable observation Windows: Provide clear, durable and reliable observation Windows for high-temperature, high-pressure and corrosive working conditions to ensure process monitoring and production safety.
Customized service
We deeply understand that standard products cannot meet all application scenarios. Therefore, we offer comprehensive customization services to ensure that the product is perfectly matched with your system
