Fused Quartz Plate / Sheet

https://www.s4r.fr/web/image/product.template/280/image_1920?unique=d0cc850

Fused quartz plate designed for laboratory thermal processing, sample support, furnace assemblies and the fabrication of custom quartz components.

The standard range covers square formats from 10 × 10 to 100 × 100 mm, with selected thicknesses from 1 to 3 mm. The material combines low thermal expansion with good dimensional stability at elevated temperature, making these plates suitable for demanding laboratory and materials-processing environments.

Other dimensions, thicknesses and custom-cut fused quartz plates can be supplied on request.

Technical Notes
• Avoid sudden temperature changes and localized mechanical impact during high-temperature use.
• Larger plates should be supported evenly to minimize concentrated mechanical stress.
• Select plate thickness according to the required rigidity, supporting arrangement and operating environment.
• Do not expose fused quartz components to hydrofluoric acid or fluoride-containing media.
