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.
高温耐性
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.

よくある質問
石英ガラスは硬くて脆い材料で、物理的、化学的性質が優れ、機械的硬度が非常に高く、電気絶縁性がよく、高温と耐食性に優れ、遅延性能が低く安定で、光透過性がよい。半導体、光学、電気、化学、航空宇宙、自動車などの分野で広く使用されている。硬くて脆い材料は加工が難しく、多くの分野で刃先の倒れが小さく、材料ロスが少なく、断面粗さが小さく、切断厚さ範囲が広い切断加工が急務となっている。石英ガラスの伝統的な切断方法は機械的切断、すなわち砥石切断である。非伝統的な切断方法には、ウォータージェット切断、電気化学放電ワイヤー切断、連続レーザー切断などがある。機械的切断はコストが低いが、ホイールと材料が接触するため工具の摩耗が大きく、材料が工具によって汚染されやすい。石英ガラスはエッジ崩壊、マイクロクラック、残留応力が発生しやすく、材料の強度や性能に影響する！曲線切断が難しく、研削や研磨などの後処理が必要。レーザー切断は材料に直接触れないため、接触応力がなく、複雑な曲線切断が可能です。ピコ秒レーザーは、スポット径が小さい、精度が高い、材料との作用時間が短い、作用面積が小さいなどの利点があり、硬くて脆い材料の加工に適しています。
