Low thermal expansion coefficient high-purity quartz flange

Low thermal expansion coefficient high-purity quartz flange is a core precision component specially developed for extreme temperatures and harsh clean environments. This product is made of ultra-high purity silica as the substrate, with an extremely low coefficient of thermal expansion and excellent thermal shock resistance. It can maintain precise dimensional stability even under severe temperature differences. As a key component for connection and sealing, it effectively prevents high-temperature deformation and impurity contamination, perfectly adapts to advanced process requirements, and supports full specification deep customization.

FAQ

Q1: What level of purity can this quartz flange achieve?

A: Our high-purity quartz flange adopts top-level purification technology, and the SiO ₂ content can usually reach 99% (4N5 grade) or even higher. Metal impurity elements are strictly controlled at the ppb level to ensure that no harmful ions are released into the reaction chamber at high temperatures.

Q2: What are the specific manifestations of the product's "low thermal expansion coefficient" in practical applications?

A: The thermal expansion coefficient of quartz glass is extremely low (about 1/20 of ordinary glass), which means that in harsh working conditions up to thousands of degrees Celsius, the flange can resist severe thermal shock without warping or cracking, thus ensuring the absolute sealing of the equipment cavity and the dimensional accuracy for long-term operation.

Q3: What specifications of customized services can your company provide? How about the delivery date?

A: We provide comprehensive customization services from standard parts to irregular parts. Whether it is a non-standard flange with a large diameter, special thickness, or complex sealing groove, precision cold processing and flame processing can be carried out according to your CAD drawings. Regular models are available in stock, and non calibrated parts rely on mature flexible production lines, with highly competitive delivery cycles.

Customer application case sharing

Optical System Upgrade Project for Large Aperture Telescope at a Large Astronomical Observatory

When the observatory was promoting the new generation of deep space observation program, some optical support flanges of the original equipment experienced slight thermal expansion and contraction deformation during the extreme temperature difference between day and night. This small size change causes deviation in the alignment of the optical path, seriously affecting the quality of high-resolution imaging and becoming a major technical challenge that restricts observation accuracy.

After introducing our customized low thermal expansion coefficient high-purity quartz flange, this problem was easily solved. We have redesigned the transition arc and installation hole positions of the flange based on its special optical platform structure, and used a special quartz substrate with ultra-low expansion coefficient. After a year of on-site operation and testing, the new flange maintained zero deformation under extreme natural conditions of extreme cold and sun exposure. It not only completely eliminated the risk of optical path deviation, but also greatly improved the stability of continuous nighttime observations, providing a solid material guarantee for the observatory to obtain high-quality cosmic data.
