Quartz Glass Rod Supplier

Quartz glass rods (including UV quartz rods, quartz crystal rods, 4 mm quartz rods, etc.) occupy an important position in many high-end fields due to their unique physical and chemical properties. As a company specializing in the production of quartz and special glass products, we have been committed to technological innovation and quality improvement since our establishment, introducing advanced production equipment at home and abroad, and continuously optimizing process flow to provide customers with high-performance quartz glass products and professional technical solutions. The following are the main advantages of quartz glass:

Excellent optical properties:
Ultraviolet quartz rods have extremely high transmittance in the deep ultraviolet to near-infrared bands, and are ideal materials for ultraviolet lasers, spectrometers and lithography equipment.
Ordinary quartz glass rods have a transmittance of nearly 92% in the visible light range, which is better than ordinary glass (about 85%).
Quartz crystal rods have a highly uniform refractive index and are suitable for precision optical systems (such as laser resonators, fiber couplers) to reduce light scattering and energy loss.

Extremely high chemical stability
Quartz rods can be exposed to corrosive media such as concentrated sulfuric acid and nitric acid for a long time, and are suitable for chemical reactors and laboratory utensils.
High-purity quartz glass rods (SiO₂ purity ≥ 99.99%) do not release metal ions during semiconductor processing, avoiding wafer contamination.

Excellent high temperature resistance
Can work for a long time at over 1000℃ (such as CVD reaction chambers, high-temperature observation windows), far exceeding ordinary glass (softening at 600℃).
Thin-diameter products such as 4mm quartz rods are not easy to deform when the temperature changes suddenly, and are suitable for high-precision thermal experiments.

Excellent electrical and insulating properties
Quartz crystal rods can be used for high-voltage insulators and semiconductor equipment supports to avoid current leakage.
Excellent performance in high-frequency electronic devices (such as microwave windows and radar antenna covers).

Biocompatibility and medical applicability
Quartz glass rods can be used in implantable medical devices (such as sensor probes) without causing rejection reactions.
Can withstand high temperature and high pressure sterilization and ethylene oxide sterilization, suitable for surgical instruments and endoscope components.

Mechanical and physical properties
The surface is scratch-resistant, and UV quartz rods can maintain smoothness for a long time in optical systems.
Quartz glass rods are lighter than metals and ceramics and are suitable for lightweight design (such as aerospace optical components).

Quartz glass rods are widely used in the following fields due to their high chemical stability, excellent optical properties and high temperature resistance:

Optics and optoelectronics

Ultraviolet quartz rods: dedicated to ultraviolet optical systems, such as ultraviolet lasers, UV spectrometers, and semiconductor lithography equipment, because they still maintain high transmittance in the deep ultraviolet band (below 190nm).

Quartz rods: used in fiber couplers, laser resonator mirror holders, optical prisms, etc., to ensure low light loss and high transmittance.

4 mm quartz rods: suitable for micro optical sensors, endoscope light guides or precision optical adjustment mechanisms.

Scientific research and laboratory equipment

Quartz glass rods are used to manufacture high-temperature reaction tubes, vacuum cavity observation windows, and plasma experimental devices because they are resistant to acid and alkali and will not pollute the experimental environment. Quartz crystal rods are used as sample holders or optical elements in X-ray diffractometers and fluorescence analyzers to ensure measurement accuracy.

Semiconductor and Electronics Industry
High-purity quartz rods are used for carriers in wafer processing and liner tubes for CVD (chemical vapor deposition) reaction chambers. They are resistant to high temperatures and do not introduce impurities. In integrated circuit manufacturing, UV quartz rods can be used as photomask substrates or optical components of UV exposure systems.

Medical Devices and Bioengineering
Quartz glass rods can be used for surgical instruments (such as laser scalpel handles), implantable sensors or microfluidic chips due to their biological inertness. 4 mm quartz rods are used as light-guiding media in dentistry or endoscopes. They are resistant to corrosion by disinfectants and have stable light transmittance.

Chemical Industry and Corrosion-Resistant Environments
In strong acids (except hydrofluoric acid), strong alkalis or high-temperature corrosive media, quartz crystal rods can be used as stirring rods, pipes or observation window materials, and their lifespan far exceeds that of metals or plastics.
