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.
Application Scenario
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.
Optical Fiber Communication
In the manufacture of optical fibers, quartz rods are used as the material for preforms, which are then drawn and processed into optical fibers. Their optical properties make them suitable for use in optical communication.
Scientific Research
Quartz rods are commonly used in laboratories for chemical experiments, spectroscopic analysis, and laser technology. Their high purity and optical properties are important for scientific research.
Industrial Manufacturing
Quartz rods are also used in industrial heating equipment, furnaces, and burners because they are capable of withstanding high-temperature environments.
Lighting Equipment
Certain types of quartz rods are used in manufacturing special lighting equipment, such as ultraviolet lamps.
Medical Devices
Due to their good biocompatibility and stability, quartz rods are used to manufacture medical devices, such as artificial blood vessels.
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.
