There are two primary methods for producing quartz rods: the continuous method and the flame fusion method (also known as the gas fusion method).
Continuous Method: In this method, quartz sand is fed from the top into a furnace, which comprises a metallic quartz crucible surrounded by electric heating elements. The quartz sand melts at high temperatures. The molten material then passes through a shaping orifice at the bottom of the crucible, producing rods, tubes, sheets, or other various specified product forms.
Flame Fusion Method: This method involves using hydrogen and oxygen to melt colorless quartz crystal. The molten material is formed into quartz glass through the melting and congealing of crystalline particles in the flame. The quartz glass is then removed from the flame through different methods and processed into quartz rods of the desired shape.
High Purity
The primary component of quartz semi-circular rods is silicon dioxide (SiO2), resulting in high purity. This characteristic makes them crucial in applications requiring high-purity materials, such as semiconductor manufacturing.
高温耐性
Quartz semi-circular rods can withstand high-temperature environments without deformation or melting, making them excellent for applications in heat treatment and high-temperature furnaces.
耐食性
These rods demonstrate excellent corrosion resistance to a variety of chemical substances, maintaining stability in harsh chemical environments.
Excellent Optical Properties
Quartz semi-circular rods possess superior optical properties, including high transparency and low light absorption, making them well-suited for applications in optical communication and spectroscopic analysis.
アプリケーション・シナリオ
Semiconductor Manufacturing
Quartz semi-circular rods are used in semiconductor manufacturing as precision components or tools in wafer processing equipment, photolithography equipment, and other semiconductor process tools. They help ensure precise wafer processing and positioning.
In various semiconductor processes like cleaning, oxidation, photolithography, etching, and diffusion, quartz semi-circular rods may act as carriers or auxiliary tools to ensure process stability and precision.
Optical Instruments
Quartz semi-circular rods are used in the manufacturing of optical instruments as a substrate for optical components such as lenses and prisms. Their excellent optical properties enable light refraction, reflection, and beam splitting.
They also play an important role in optical equipment like spectrometers and thermal imagers.
Laboratory and Scientific Research
In laboratories, quartz semi-circular rods are often used in chemical experiments and spectroscopic analysis as stirring rods or reaction vessel components due to their chemical stability and inertness to most chemical substances.
In scientific research, they are used in high-precision measurement and analysis instruments to ensure the accuracy and reliability of experimental results.
Other Fields
Quartz semi-circular rods are used to make mechanical parts like pressure gauges and high-precision instruments used in high-temperature and high-pressure environments.
In optical fiber communication, they may be a part of the optical fiber preform, which is processed into optical fibers through specific techniques.
The manufacturing process of quartz rods primarily involves melting quartz sand into hollow quartz preforms using a plasma flame. These preforms are then mechanically cold-worked into thick-walled quartz tubes. Finally, a medium-frequency induction heating non-contact secondary shaping technology is used to produce the quartz rods. This meticulous process ensures the quartz rods possess high purity, low hydroxyl content, high dimensional accuracy, and a superior surface finish free of defects.
In the electronics industry, quartz rods are primarily utilized as substrates for semiconductor materials and as bases for electronic components. Their excellent electrical insulation and thermal stability make them ideal for use in high-frequency circuits and sensors, as well as other high-precision electronic devices. Quartz rods are also crucial for the production of photomasks and glass chips, which are vital for enhancing electronic device performance.
Quartz rods exhibit an extremely low coefficient of thermal expansion and excellent resistance to thermal shock.
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。
