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.
High-Temperature Resistance
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.
Corrosion Resistance
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.
Application Scenario
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.

Frequently asked questions
Quartz glass is a hard and brittle material with excellent physical and chemical properties, extremely high mechanical hardness, good electrical insulation, high temperature and corrosion resistance, low and stable delay performance, good light transmittance, etc. It is widely used in semiconductors, optics, electricity, chemistry, aerospace, automobiles and other fields. Hard and brittle materials are difficult to process, and many fields urgently need cutting processes with small edge collapse, less material loss, low cross-section roughness, and a wide cutting thickness range. The traditional cutting method of quartz glass is mechanical cutting, that is, wheel cutting. Non-traditional cutting methods include water jet cutting, electrochemical discharge wire cutting, continuous laser cutting, etc. Mechanical cutting has low cost, but the contact between the wheel and the material causes large tool wear, and the material is easily contaminated by the tool. Quartz glass is prone to edge collapse, microcracks, and residual stress, which affects the strength and performance of the material! It is difficult to achieve curve cutting and requires post-processing, such as grinding and polishing. Laser cutting does not directly contact the material, has no contact stress, and can perform complex curve cutting. Picosecond laser has the advantages of small spot diameter, high precision, short action time with the material, and small action area, and is suitable for the processing of hard and brittle materials.
