Usage Guide for Clear Quartz Glass Plate
Handling Precautions
Handle quartz plates with care to avoid impacts or drops that could cause breakage. Always wear clean, lint-free gloves when handling plates for high-temperature applications to prevent contamination from fingerprints.
Cleaning & Maintenance
Clean plates thoroughly before high-temperature use. For optical applications, use isopropyl alcohol or acetone with lint-free wipes. Avoid abrasive cleaners that could scratch the surface and affect optical properties.
Temperature Limitations
Do not exceed the maximum operating temperature (1450°C for short-term use). For applications above 1100°C, consult with our engineers regarding appropriate thickness and edge treatment to prevent deformation.
Chemical Compatibility
Quartz is acidic in nature. At high temperatures, strictly avoid contact with alkaline substances (sodium/potassium compounds, water glass, asbestos) as these will significantly degrade performance and potentially cause failure.

FAQ
Q: What is the difference between the JGS-1, JGS-2, and JGS-3 quartz glass grades?
A: JGS-1 is far UV grade quartz with high OH content (2000 PPM), offering excellent transmission down to 185nm. JGS-2 is UV grade with moderate OH content (100-200 PPM), suitable for 220-2500μm applications. JGS-3 is IR grade with minimal OH content, optimized for 260-3500μm wavelength transmission. The choice depends on your specific wavelength requirements.
Q: How do I clean quartz glass plates without damaging them?
A: For optical applications, use isopropyl alcohol or acetone with lint-free wipes. For general cleaning, a mild detergent solution followed by thorough rinsing with deionized water is recommended. Avoid abrasive cleaners and tools that could scratch the surface. For stubborn contaminants, ultrasonic cleaning in appropriate solutions is effective.
Q: Are your quartz glass plates suitable for semiconductor applications?
A: While our quartz glass plates meet many requirements for semiconductor-adjacent applications, we do not currently serve the high-end semiconductor industry that requires ultra-high purity (99.9999%) and specialized certifications. Our products are suitable for research, optical, laboratory, and industrial applications with purity levels up to 99.995%.
Q: Can you drill holes or create custom shapes in quartz glass plates?
A: Yes, we offer precision drilling, cutting, and machining services for quartz glass plates. We can create custom shapes, holes, slots, and other features according to your technical drawings. Our capabilities include water jet cutting, ultrasonic drilling, and precision grinding to achieve complex geometries while maintaining material integrity.
Q: How do quartz glass plates compare to borosilicate glass?
A: Quartz glass offers significantly higher temperature resistance (1100°C vs 500°C for borosilicate), superior UV transmission, better chemical resistance, and lower thermal expansion. Borosilicate is more cost-effective for applications that don’t require these advanced properties. For high-temperature, optical, or chemically demanding applications, quartz glass is the superior choice.
