Quartz source bottles are typically made from high-purity quartz glass, which provides excellent resistance to high temperatures, corrosion, and strong acids. They are primarily used for the storage and transfer of high-purity chemical raw materials such as phosphorus oxychloride (POCl3). Additionally, they are used as reaction vessels or source bottles during various chemical reactions in laboratories. The cleanroom packaging design of quartz source bottles ensures the purity of the raw materials and prevents contamination.

アプリケーション・シナリオ
半導体産業
Semiconductor Material and Device Production: Quartz source bottles are indispensable materials in semiconductor production, frequently used in crucibles, boats, furnace core tubes, and bell jars for growing germanium and silicon single crystals. These components need to withstand high temperatures and corrosive environments, making the high-temperature and corrosion resistance of quartz source bottles ideal.
Cleaning and Diffusion: In semiconductor cleaning and diffusion processes, quartz source bottles are also commonly used as cleaning tanks and diffusion tubes to ensure process stability and precision.
Optical Technology
Optical Instruments and Equipment: Due to their excellent optical properties, quartz source bottles are widely used in making prisms and lenses for optical instruments such as ultrasonic delay lines in radar, infrared tracking and ranging equipment, infrared cameras, communication devices, spectrographs, and spectrophotometers.
Large Astronomical Telescopes: Quartz glass, due to its high transparency and low thermal expansion coefficient, is also used in manufacturing reflective windows for large astronomical telescopes to enhance the telescope’s observation precision and stability.
New Energy Sector
Solar Energy: Quartz source bottles are also used in the solar energy sector, for example, as containers or trays for carrying and supporting solar cells during production.
研究室とリサーチ
Laboratory Containers: Due to their chemical stability and high-temperature resistance, quartz source bottles are often used as laboratory containers, such as for collecting and processing chemical waste.
Research Equipment: In research settings, quartz source bottles are also used to manufacture various precision components for research equipment to meet the needs of scientific studies.
Quartz source bottles have a silicon dioxide (SiO2) content of up to 99.995%, which eliminates risks associated with glass inhomogeneity (including layering) and the leaching of problematic metal ions.
Quartz source bottles exhibit extremely high stability at high temperatures and do not easily deform. Their low thermal expansion coefficient and excellent thermal shock resistance allow them to maintain their shape and structural integrity under drastic temperature changes.
Ensuring Experimental Accuracy: Quartz source bottles can remain stable at temperatures up to 1100°C. This means that in high-temperature experiments, quartz source bottles serve as reliable containers, ensuring that the accuracy of the experimental results is not compromised by thermal deformation or decomposition of the container.
Enhancing Experimental Safety: Quartz source bottles possess outstanding thermal shock resistance, meaning they are not prone to cracking even under rapid temperature changes. This significantly reduces safety risks in high-temperature experiments, protecting laboratory personnel and 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。
