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.
Superior Corrosion Resistance
Quartz rods are made from pure natural quartz stone, which provides exceptional resistance to corrosion, enabling long-term use in harsh environments such as acids and alkalis without being easily damaged.
High-Temperature Stability
The quartz composition of these rods provides excellent resistance to high temperatures, allowing them to withstand hot water, steam, and similar conditions without deformation or embrittlement.
Smooth and Flat Surface
Through precise processing, the quartz rod surfaces are smooth and flat, making them less prone to accumulating dirt, and thus are easy to clean and maintain.
igh Hardness and Compressive Strength
Quartz rods are resistant to external impacts and wear, resulting in a long service life.
Anwendungsszenario
Semiconductor Manufacturing
Quartz rods are used in the semiconductor industry for manufacturing wafer processing equipment, photolithography equipment, and other semiconductor process tools. Their ability to withstand high temperatures and chemical corrosion is critical in semiconductor manufacturing processes.
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.
Häufig gestellte Fragen
Quarzglas ist ein hartes und sprödes Material mit ausgezeichneten physikalischen und chemischen Eigenschaften, extrem hoher mechanischer Härte, guter elektrischer Isolierung, hoher Temperatur- und Korrosionsbeständigkeit, geringer und stabiler Verzögerungsleistung, guter Lichtdurchlässigkeit usw. Es findet breite Anwendung in der Halbleiterindustrie, Optik, Elektrizität, Chemie, Luft- und Raumfahrt, Automobilindustrie und anderen Bereichen. Harte und spröde Werkstoffe sind schwer zu bearbeiten, und in vielen Bereichen werden dringend Schneidverfahren mit geringem Kanteneinbruch, geringem Materialverlust, geringer Querschnittsrauheit und einem großen Schnittdickenbereich benötigt. Das traditionelle Schneidverfahren für Quarzglas ist das mechanische Schneiden, d. h. das Scheibenschneiden. Zu den nicht-traditionellen Schneidverfahren gehören Wasserstrahlschneiden, elektrochemisches Drahterodieren, kontinuierliches Laserschneiden usw. Das mechanische Schneiden ist kostengünstig, aber der Kontakt zwischen der Scheibe und dem Material verursacht einen hohen Werkzeugverschleiß, und das Material wird leicht durch das Werkzeug verschmutzt. Quarzglas neigt zu Kanteneinbrüchen, Mikrorissen und Eigenspannungen, was die Festigkeit und Leistung des Materials beeinträchtigt! Das Schneiden von Kurven ist schwierig und erfordert Nachbearbeitungen wie Schleifen und Polieren. Das Laserschneiden kommt nicht direkt mit dem Material in Berührung, hat keine Kontaktspannungen und kann komplexe Kurvenschnitte durchführen. Der Pikosekundenlaser hat die Vorteile eines kleinen Punktdurchmessers, einer hohen Präzision, einer kurzen Einwirkungszeit auf das Material und eines kleinen Einwirkungsbereichs und eignet sich für die Bearbeitung von harten und spröden Materialien.
