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.
고온 내성
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.
화학적 안정성
Quartz discs demonstrate excellent resistance to most chemicals, with the exception of hydrofluoric acid, making them very stable for chemical laboratory and industrial uses.
낮은 열팽창 계수
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.

자주 묻는 질문
석영 유리는 우수한 물리적 및 화학적 특성, 매우 높은 기계적 경도, 우수한 전기 절연성, 고온 및 내식성, 낮고 안정적인 지연 성능, 우수한 빛 투과율 등을 갖춘 단단하고 부서지기 쉬운 소재입니다. 반도체, 광학, 전기, 화학, 항공우주, 자동차 및 기타 분야에서 널리 사용됩니다. 단단하고 부서지기 쉬운 재료는 가공이 어렵고 많은 분야에서 가장자리 붕괴가 적고 재료 손실이 적으며 단면 거칠기가 낮고 절단 두께 범위가 넓은 절단 공정이 절실히 필요합니다. 석영 유리의 전통적인 절단 방법은 기계식 절단, 즉 휠 절단입니다. 비 전통적인 절단 방법에는 워터젯 절단, 전기 화학 방전 와이어 절단, 연속 레이저 절단 등이 포함됩니다. 기계식 절단은 비용이 저렴하지만 휠과 재료 사이의 접촉으로 인해 공구 마모가 크고 재료가 공구에 의해 쉽게 오염됩니다. 석영 유리는 가장자리 붕괴, 미세 균열 및 잔류 응력이 발생하기 쉬우므로 재료의 강도와 성능에 영향을 미칩니다! 곡선 절단이 어렵고 연마 및 연마와 같은 후처리가 필요합니다. 레이저 절단은 재료에 직접 접촉하지 않고 접촉 응력이 없으며 복잡한 곡선 절단을 수행할 수 있습니다. 피코초 레이저는 작은 스폿 직경, 고정밀, 재료와의 짧은 작용 시간, 작은 작용 면적의 장점을 가지고 있으며 단단하고 부서지기 쉬운 재료의 가공에 적합합니다.
