High Purity and Transparency
Quartz discs are made from high-purity silicon dioxide and exhibit exceptional transparency, particularly across the ultraviolet to infrared spectral range. This makes them ideally suited for optical applications.
Resistencia a altas temperaturas
Quartz discs can withstand extremely high temperatures, with a softening point around 1730°C, and can be used continuously at 1100°C, and can tolerate short-term temperatures up to 1450°C. This makes them suitable for high-temperature environments.
Chemical Stability
Quartz discs demonstrate excellent resistance to most chemicals, with the exception of hydrofluoric acid, making them very stable for chemical laboratory and industrial uses.
Low Thermal Expansion Coefficient
Quartz discs have a very low thermal expansion coefficient, which means their dimensions change very little with temperature variations. This is essential for applications requiring precise dimensional control, such as in precision instruments and high-temperature equipment.

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.
