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.
Resistencia a altas temperaturas
Quartz glass, as the primary material for these view windows, exhibits extremely high-temperature resistance. Its softening point reaches approximately 1730°C, and it can be used continuously at 1100°C, with short-term use up to 1450°C. This enables high-temperature quartz view windows to withstand various high-temperature environments without deformation or fracture.
High Light Transmission
Quartz glass typically has a light transmittance greater than 90%, with transmittance exceeding 93% in the visible light range, and a high transmittance in the UV spectral range. This high light transmission allows high-temperature quartz view windows to provide a clear view of production processes within high-temperature equipment.
Chemical Stability
Quartz glass possesses excellent chemical stability, with almost no reaction to other acids, and acid resistance that is 30 times greater than ceramics and 150 times greater than stainless steel. This allows high-temperature quartz view windows to operate reliably over long periods in corrosive environments, such as acids and alkalis.
Low Thermal Expansion Coefficient
Quartz glass has a very low thermal expansion coefficient and can withstand sudden temperature changes. Even when heated to approximately 1100°C and then quickly placed into room-temperature water, it will not fracture.

Quartz view windows have good light transmission across the entire spectrum from ultraviolet to infrared, with a visible light transmittance exceeding 93%. In the ultraviolet spectral range, the transmittance can reach over 80%.
Quartz view windows exhibit high dielectric strength and very low electrical conductivity (low dielectric loss). Even at high temperatures, their electrical conductivity and dielectric loss remain lower than those of many other materials, making them suitable as high-frequency and voltage insulation materials under high-temperature and mechanical stress conditions.
Quartz view windows possess excellent chemical stability and, with the exception of hydrofluoric acid, exhibit almost no chemical reactions with other acids, and have excellent corrosion resistance.
Preguntas más frecuentes
El vidrio de cuarzo es un material duro y quebradizo con excelentes propiedades físicas y químicas, dureza mecánica extremadamente alta, buen aislamiento eléctrico, resistencia a altas temperaturas y a la corrosión, rendimiento de retardo bajo y estable, buena transmitancia luminosa, etc. Se utiliza ampliamente en semiconductores, óptica, electricidad, química, aeroespacial, automoción y otros campos. Los materiales duros y quebradizos son difíciles de procesar, y muchos campos necesitan urgentemente procesos de corte con un pequeño colapso del borde, menos pérdida de material, baja rugosidad de la sección transversal y un amplio rango de grosor de corte. El método de corte tradicional del vidrio de cuarzo es el corte mecánico, es decir, el corte por disco. Los métodos de corte no tradicionales incluyen el corte por chorro de agua, el corte por hilo de descarga electroquímica, el corte por láser continuo, etc. El corte mecánico tiene un bajo coste, pero el contacto entre la rueda y el material causa un gran desgaste de la herramienta, y el material es fácilmente contaminado por la herramienta. El vidrio de cuarzo es propenso al colapso de los bordes, las microfisuras y la tensión residual, lo que afecta a la resistencia y el rendimiento del material. Es difícil conseguir un corte curvo y requiere un tratamiento posterior, como esmerilado y pulido. El corte por láser no entra en contacto directo con el material, no tiene tensión de contacto y puede realizar cortes curvos complejos. El láser de picosegundos tiene las ventajas de un diámetro de punto pequeño, alta precisión, tiempo de acción corto con el material y área de acción pequeña, y es adecuado para el procesamiento de materiales duros y quebradizos.
