Fabricated Polishing High Purity Fused Quartz Wafers Customizable Custom Size

Product Name: High Purity Quartz Disc
Dimension: Radius R12.5mm (Outer Diameter Φ25mm), Thickness 5mm; size and polishing grade customizable

Fabricated and polished from high purity quartz, with excellent light transmittance, high temperature resistance, acid and alkali resistance and zero impurity precipitation. Widely used as semiconductor wafer supporting gaskets, optical viewing windows, cover plates for laboratory reactors, photocatalytic light-transmitting lenses, sealed observation sheets for high-temperature furnaces and optical substrates for testing equipment. It isolates liquid and high-temperature gas while transmitting UV and visible light, suitable for high-cleanliness scenarios including microelectronics, new energy, chemical experiments and environmental monitoring.

1. Superior Optical Transmittance: High permeability for UV and visible light with low light loss for clear observation.

2. Outstanding Thermal Stability: Stable long-term operation at 200℃~1100℃, crack-resistant under thermal shock.

3. Strong Chemical Corrosion Resistance: Resist long-term erosion by hydrofluoric acid, concentrated strong acids and alkalis.

4. Ultra-High Cleanliness: High-purity material free of heavy metal leaching to avoid contamination of wafers and high-purity reagents.

5. Precision Polishing: Double-sided mirror polishing with high flatness for tight sealing; further processing such as cutting and slotting is available.
