アプリケーション・シナリオ
High-Temperature Reaction Vessels
Due to the high-temperature resistance of quartz glass, they can be used as vessels for high-temperature chemical reactions, such as in pyrolysis or calcination processes.
Semiconductor Manufacturing Equipment
In the semiconductor industry, they can be used as reaction tubes in CVD (Chemical Vapor Deposition) or diffusion furnaces for manufacturing high-quality semiconductor materials.
High-Purity Sample Handling
Can be used as containers for handling high-purity samples, such as in pharmaceuticals and biotechnology, to prevent sample contamination and maintain their purity.
Optical Analysis Instrument Components
Utilizing the good light transmission properties of quartz glass, they can be used as components in optical analysis instruments, such as sample cells or reaction vessels in spectrometers and spectrophotometers.
Typically, this quartz tube can withstand temperatures up to 1200°C, and in some special cases, even up to 1600°C. However, the specific temperature resistance depends on the quality of the quartz glass and the environmental conditions. Please refer to the product specifications for accurate values.
Quartz glass has very good chemical inertness and can withstand most acids, bases, and organic solvents. However, please avoid contact with highly corrosive substances such as hydrofluoric acid (HF), hot concentrated alkalis, and molten alkali metals, which may corrode the quartz glass.
The flange connection, when fitted with appropriate gaskets, provides good gas-tight and liquid-tight sealing. It is crucial to choose a gasket material (such as PTFE, Viton, etc.) that matches the application scenario. Also, ensure that the flanges are properly aligned and the bolts are tightened to the specified torque for optimal sealing.

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。
