Fused Quartz Disc

Fused quartz disc intended for laboratory thermal processing, sample support, component fabrication and high-temperature assemblies.

The standard range covers diameters from 5 to 100 mm with selected thicknesses from 1 to 3 mm, providing practical formats for small samples through larger furnace and materials-processing applications. Fused quartz offers low thermal expansion and good dimensional stability under elevated-temperature conditions.

Other diameters, thicknesses and custom-cut dimensions can be supplied on request.

The standard range covers round fused quartz discs from 5 to 100 mm diameter, with thicknesses selected according to the size and intended laboratory use. Smaller formats are suitable for compact sample supports and fabricated components, while larger diameters provide additional working area for furnace and materials-processing assemblies. Alternative diameters and thicknesses can be produced for non-standard requirements.

Technical Notes

• Avoid sudden temperature changes and localized mechanical impact during high-temperature use.

• Support larger discs evenly to minimize concentrated mechanical stress.

• Select thickness according to the required rigidity, support conditions and operating environment.

• Do not expose fused quartz components to hydrofluoric acid or fluoride-containing media.
