At Technical Glass Products (TGP), we specialize in advanced glass and ceramic materials engineered for high-performance applications. Among our core offerings are Fused Quartz Ground & Polished Plates & Discs—precision-finished components designed to perform reliably in demanding thermal, optical, and chemical environments.
These components combine the exceptional properties of fused quartz with tight dimensional control and refined surface finishes, making them a trusted solution across a wide range of technical industries.
What Are Fused Quartz Ground & Polished Plates & Discs?
Fused quartz is a high-purity silica material valued for its extremely low thermal expansion, excellent chemical resistance, and outstanding optical transmission from ultraviolet through infrared wavelengths. These inherent properties make fused quartz ideal for applications where thermal stability, cleanliness, and optical clarity are critical.
Ground & polished plates and discs are flat fused quartz components that undergo a multi-step finishing process:
- Precision grinding to achieve exact thicknesses, flatness, and dimensional tolerances
- Polishing to produce smooth, uniform surfaces with minimal defects
The result is a highly stable, flat component suitable for precision optical, thermal, and mechanical applications where consistency and performance are essential.
Common Uses for Ground & Polished Quartz Plates & Discs
Because of their purity, surface quality, and thermal performance, fused quartz plates and discs serve as foundational components in many advanced systems, including:
Optical & Photonic Applications
- Optical windows and substrates
- Laser system components
- Precision measurement and imaging equipment
The polished surfaces allow for high light transmission with minimal distortion, making them ideal for sensitive optical systems.
Semiconductor & Electronics Manufacturing
- Wafer handling and processing fixtures
- High-temperature process components
- Chemically resistant substrates used in cleanroom environments
Fused quartz’s ability to withstand extreme temperatures and aggressive process chemistries makes it well suited for semiconductor fabrication.
High-Temperature & Thermal Processing
- Furnace viewports and covers
- Thermal process barriers and plates
- Components exposed to rapid temperature cycling
The low coefficient of thermal expansion helps maintain dimensional stability even under intense heat.
