Quartz tubes, due to their excellent high temperature resistance, transparency, and electrical insulation properties, are not only the core consumables of environmental testing equipment, but also an indispensable "industrial blood" in the high-end manufacturing field. From precision machining of semiconductor chips to signal transmission in fiber optic communication, and to energy conversion in special lighting, quartz tubes, with their irreplaceable physical and chemical properties, are solving technological bottlenecks in multiple cutting-edge industries worldwide.

User pain point priority: FAQ Q&A format

Q1: What should I do if the furnace tube is frequently damaged during the semiconductor diffusion process, resulting in a decrease in product yield?

A: Our high-purity large-diameter quartz tubes have excellent high temperature resistance and thermal stability (with extremely low coefficient of thermal expansion), and can be used for a long time at around 1200 ℃ without deformation or crystallization. This can significantly reduce the frequency of furnace tube maintenance, ensuring that wafers are not contaminated by particles during diffusion, thereby improving yield.

Q2: We produce special lighting fixtures and need to ensure UV penetration rate without causing burns to the operators. Do we have suitable materials?

A: Yes, there is. We can provide customized UV filtering quartz tubes and ozone free quartz tubes. The former can filter out harmful 190-320nm ultraviolet rays to the human body, while the latter can efficiently pass through the 253.7nm sterilization band, perfectly meeting the optical requirements of medical sterilization and curing equipment.

Q3: I am looking for basic materials that can be used for fiber preform rods, with extremely low hydroxyl content and ultra-high purity requirements. Can you do it?

A: Of course you can. We use advanced synthetic melting technology to provide high-purity quartz tubes with extremely low hydroxyl content (up to 5ppm). This material is an ideal substrate for manufacturing special optical fibers such as fluorine doped tubes and rare earth doped fibers, ensuring low loss transmission of optical signals.

Q4: Our experimental setup has a special structure, and standard straight tubes cannot be installed. Can we provide irregular machining?

A: Absolutely possible. We provide full process customization services and support customized drawings. Whether it's complex U-tubes, stepped tubes, flanged tubes, or quartz reaction vessels, we can achieve them through precise hot and cold processing techniques.

Core application areas: not only detection, but also the cornerstone of high-end manufacturing

Quartz material plays a key role in the following three core areas due to its high temperature resistance, corrosion resistance, high transparency, and excellent electrical insulation.

1. Semiconductor and Photovoltaic Industries: "Reaction Containers" for Precision Manufacturing

In semiconductor and integrated circuit manufacturing, quartz components are key consumables for core processes such as diffusion, oxidation, and etching.

-Application scenarios: Silicon wafer diffusion furnace tube, quartz boat, quartz bell jar, etching ring.

-Product advantages: Our product has extremely high chemical purity, can withstand strong acid and alkali (except hydrofluoric acid) corrosion, and does not react with silicon wafers at high temperatures, ensuring the accuracy of circuit characterization.

-Customization service: For the needs of 8-inch and 12 inch wafer fabs, we provide customized high-quality quartz tubes and non-standard shaped parts with large diameters (up to 600mm in outer diameter).

2. Special light sources and UV curing: the "perfect channel" for energy

Quartz tube is the preferred material for manufacturing various light sources because it can efficiently transmit a wide spectrum from ultraviolet to infrared.

-Application scenarios: UV sterilization lamps, automotive xenon lamps, semiconductor lithography light sources, infrared heating lamps.

-Product advantage: Depending on the application, we can provide materials with different hydroxyl content. Low hydroxyl tubes are used for infrared heating to ensure thermal efficiency; Ozone free tubes are used for water treatment sterilization to avoid environmental pollution.

-Customized service: We provide special performance tubes such as UV filtering and ozone free, with specifications ranging from 1.5mm to 160mm.

3. Fiber optic communication and laser technology: the "nerve fibers" of the information age

Quartz material is the cornerstone of modern fiber optic communication. In recent years, with the development of laser technology, highly doped quartz tubes have become a new research hotspot.

-Application scenarios: Fiber preform, fluorine doped tube, high-power laser.

-Product advantage: Our successfully mass-produced semiconductor grade high-purity quartz tube is the foundation for preparing fluorine doped quartz tubes. By precise fluorine doping, the numerical aperture (NA) of optical fibers can be significantly improved, enhancing fiber coupling efficiency and meeting the needs of 5G communication and laser guidance.

-Customized service: For special fiber optic customers, we can cooperate to adjust the doping concentration and geometric dimensions of quartz tubes, and support R&D level small batch customization.

Real customer cases:

Case 1: Solving the problem of "tube bursting" in the production of photovoltaic cells

-Customer background: A large photovoltaic module manufacturer in East China (anonymous) frequently experiences quartz furnace tube explosions in the diffusion process section, resulting in production line shutdowns and huge monthly losses.

-Requirement analysis: Ordinary quartz tubes have insufficient thermal stability and cannot withstand frequent temperature rise and fall cycles.

-Solution: We have provided custom thickened large-diameter high-purity quartz tubes and optimized the annealing process to eliminate internal stress in the tubes.

-Final effect: The service life of the furnace tube has been extended by more than three times, the downtime of the production line has been reduced by 90%, and the annual procurement cost of the customer has actually been reduced by 40%.

Case 2: Assisting research institutes in overcoming bottleneck technologies

-Customer background: A laser technology research institute (anonymous) urgently needs a cladding quartz tube with specific rare earth doping function when developing high-power single frequency fiber lasers.

-Requirement analysis: Universal quartz tubes cannot achieve uniform doping of high concentration rare earth ions, which affects the laser output efficiency.

-Solution: We cooperated with its research group to provide a quartz tube for active optical fiber with high SiO ₂ content glass by improving the coating process of sol gel combined with the inner wall of quartz tube.

-Final result: Successfully helped the customer achieve high concentration doping of Yb ⊃3; ⁺ ions, resulting in a laser with a signal-to-noise ratio of up to 70dB, and successfully passed the project acceptance.
