Quartz Glass Tube Supplier

Quartz glass tube is a tubular material made of high-purity quartz glass (SiO₂) as the main raw material. It has excellent physical, chemical and optical properties and is widely used in optics, chemical industry, electronics, semiconductors, electric light sources and other fields.

The SiO₂ content of transparent quartz tube is ≥99.9%, and the optical transmittance is >93%, which is suitable for high-precision optical instruments and ultraviolet-infrared light transmission applications. The hydroxyl (OH⁻) content of dehydroxylated quartz tube can be controlled below 10ppm (can reach below 5ppm after vacuum dehydroxylation), which is suitable for low hydroxyl demand scenarios such as high-pressure mercury lamps, sodium lamps, and metal halide lamps.

High temperature resistant, extremely low thermal expansion coefficient, strong thermal shock resistance, can withstand drastic temperature changes without breaking. Good thermal stability, suitable for harsh environments such as high-temperature reactors and semiconductor diffusion furnaces.

Acid resistant and corrosion resistant (except hydrofluoric acid and hot phosphoric acid), suitable for corrosive medium transmission in the chemical industry.

We provide transparent quartz tubes, milky quartz tubes, colored quartz tubes, quartz bends, spherical quartz tubes, special-shaped quartz tubes, double-hole quartz glass tubes, etc. to meet the needs of different application scenarios.

There are two main manufacturing processes for quartz glass tubes: melting and drawing and processing. Melting and drawing directly draws tubes by melting high-purity quartz sand at high temperature, which is suitable for standard specifications. Processing and forming performs secondary processing (such as bending and welding) on ​​the fused quartz glass to produce special-shaped or complex structure pipes.

We are a high-tech enterprise focusing on the research and development, production and sales of high-end quartz glass and special optical materials. We are committed to providing high-purity, high-performance and high-reliability quartz glass products and customized solutions for global customers. The company has advanced production equipment, strict quality control system and professional technical team. Our products are widely used in semiconductors, optics, chemicals, new energy, medical, electric light sources and other fields, and are exported to international markets such as Europe, America, Japan and South Korea.

Quartz glass tubes are widely used in key components such as laser optical windows and reflector tubes due to their high transmittance and excellent UV-IR transmission performance to ensure stable laser transmission. In the field of precision optics, they are used to manufacture optical lenses and prisms for telescopes and microscopes. At the same time, they are used as support tubes for optical fiber preforms to improve the quality of communication signals. Its excellent UV transmission properties also make it an ideal choice for sterilization lamps and light-curing equipment.

High-purity quartz glass tubes are key materials for semiconductor manufacturing. They are used in diffusion furnace tubes and CVD reaction tubes for wafer processing to ensure that the high-temperature process environment is pollution-free. They play an important role in plasma etching equipment and IC packaging, and provide reliable support for PECVD equipment in the photovoltaic industry.

The corrosion resistance of quartz glass makes it the first choice for strong acid medium delivery pipelines and is widely used in chemical reaction equipment. It is used in sterilization equipment and analytical instruments in the medical field, and its biocompatibility is also suitable for special medical devices.

Low-hydroxyl quartz tubes are the core materials of HID light sources such as high-pressure mercury lamps and metal halide lamps. Their high temperature resistance makes them an ideal choice for halogen lamp and UV LED packaging, and they are widely used in various professional lighting fields.

Quartz glass products play a key role in solar silicon wafer growth furnaces and water electrolysis hydrogen production equipment, while providing reliable solutions for industrial waste gas treatment systems.

As the preferred material for scientific research experiments, quartz glass products are widely used in high-temperature experimental devices, spectral analysis instruments and vacuum systems, providing reliable support for scientific research.
