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.
耐食性
Quartz glass resists most acids, except hydrofluoric acid, and has acid resistance 30 times greater than ceramics and 150 times greater than stainless steel.

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。
