JGS1
Commonly known as UV-grade fused silica, this material exhibits exceptionally low dispersion and very high transmittance in the ultraviolet (UV) spectral range.
JGS2
Similar to JGS1, but may have variations in specific performance parameters such as transmittance and thermal expansion coefficient, depending on the manufacturer’s standards.
JGS3
Typically used in applications requiring higher purity or specialized performance characteristics. Specific performance parameters can vary based on the manufacturer.
High Heat Resistance
Quartz glass softens around 1730°C, can be used continuously at 1100°C, and briefly up to 1450°C.
Low Thermal Expansion
Quartz discs have a very low thermal expansion, resisting cracking from quick temperature changes.
Corrosion Resistance
Quartz glass resists most acids, except hydrofluoric acid, and has acid resistance 30 times greater than ceramics and 150 times greater than stainless steel.
Excellent Light Transmission
Quartz discs transmit light well across the UV to IR range, with over 93% visible light transmission and over 80% maximum UV transmission.
Application Scenario
A low thermal expansion coefficient means that quartz discs/wafers maintain dimensional stability under temperature changes, which is crucial for high-technology applications requiring precise control.
Quartz discs/wafers have good light transmission, especially in the ultraviolet to infrared spectral range, making them ideal materials for optical applications.
Quartz discs are excellent electrical insulators, which makes them very useful in the electronics and semiconductor industries
