Whitepaper: Precision Quartz Ring Engineering in High-Temperature Vacuum Environments
In modern industrial applications—ranging from semiconductor wafer processing chambers in Pays de la Loire to aerospace composites manufacturing—fused quartz rings perform essential mechanical, optical, and thermal isolation duties. Selecting the correct grade and fabrication methodology is critical to avoiding micro-fractures, premature crystallization (devitrification), and process contamination.
JGS1 Synthetic Silica
Deep UV transmission down to 185 nm. Virtually bubble-free with ppm-level metal contaminants, essential for laser photolithography and semiconductor wafer rings.
JGS2 Optical Fused Quartz
Standard quartz grade melted from purified natural rock crystal. Superior transmission across 220–2500 nm, ideal for viewport sight glasses and vacuum flanges.
JGS3 Infrared Silica
OH content below 5 ppm. Eliminates water absorption bands up to 3500 nm, chosen for IR heat emitter rings, combustion viewports, and thermal barriers.
Thermal & Mechanical Integrity: Our fused quartz possesses an ultra-low linear thermal expansion coefficient (CTE of 5.5 × 10⁻⁷ /°C). This allows rapid thermal cycling between 20°C and 1100°C without risk of catastrophic thermal shock failure. Annealed at 1215°C and with a softening threshold above 1680°C, our custom OEM/ODM rings withstand continuous aggressive plasma etching (fluorinated chemistry) and thermal furnace operation.
