as per customer's requirement
As a professional quartz products manufacturer, the 5-600mm round quartz tubes we produce are made from high-purity natural quartz sand through advanced melting technology. The product diameter range covers from 5mm to 600mm, and the wall thickness can be customized according to application requirements. It features outstanding thermal stability, chemical inertness and optical performance, meeting the global demand for high-quality quartz materials in various industries.
Core product advantages
1. The material has excellent performance
- High purity guarantee: SiO₂ content ≥99.99%, key impurity elements (Al, Fe, Na, etc.) controlled at the ppm level
- Excellent thermal stability: The softening point is as high as 1730℃, and it can be used for a long time at 1200℃. The coefficient of thermal expansion is extremely low (5.5×10⁻⁷/℃)
- Outstanding optical properties: It has excellent light transmittance in the ultraviolet to infrared bands (170nm-3500nm), with a light transmittance in the ultraviolet region exceeding 90%
2. Precision manufacturing process
Continuous melting and temperature-controlled tube drawing technology is adopted to ensure dimensional accuracy (diameter tolerance ±0.5mm, wall thickness tolerance ±0.1mm).
Professional annealing treatment eliminates internal stress, enhances mechanical strength and thermal shock stability
The surface can be polished, matte, coated and other treatments to meet different application requirements
Main application fields
The semiconductor and photovoltaic industry
Diffusion tubes and carrier tubes in the wafer manufacturing process
Quartz boats and furnace tubes for photovoltaic cell production

The problem we have solved
1. The problem of replacing imports
Provide import substitution solutions of the same quality but with a cost reduction of 20-30% for customers in Europe, America, Japan and South Korea, and solve the problem of geographical restrictions in the supply chain.
2. Special application matching challenges
Through customized design, we address the special size and performance requirements that standard products cannot meet, avoiding the high costs of equipment modification for customers.
3. Performance consistency challenge
A strict process control and inspection system resolves the issue of performance fluctuations between batches, ensuring the stability of customers' production processes.
4. Reliability challenges in high-temperature environments
High-purity materials and professional annealing processes solve the problems of quartz tubes being prone to cracking and having a short lifespan in environments with rapid cooling and heating.
Customer application case
Case One: A German photovoltaic equipment manufacturer
Challenge: A super-large quartz tube with a diameter of 350mm and a length of 2500mm is required as the inner lining of the diffusion furnace. It is necessary to ensure that it does not deform or contaminate the silicon wafers at high temperatures.
Solution: We custom-made quartz tubes with low alkali metal content and wall thickness uniformity controlled within ±0.08mm, and the inner walls were specially polished to reduce the deposition of polycrystalline silicon.
Achievements: The customer's production efficiency has increased by 15%, and the service life of the quartz tube has been extended to 1.8 times that of the original product. It has been purchased continuously for three years.
Case Two: Materials Laboratory of an American University
Challenge: A variety of small-batch special-specification quartz tubes (with diameters ranging from 8 to 50mm) are required for high-temperature experiments, demanding rapid delivery and stable performance.
Solution: We have activated a rapid sampling channel, providing samples of five different specifications within two weeks, along with detailed data on the coefficient of thermal expansion and light transmittance.
Achievement: The laboratory has successfully completed the sintering experiment of new ceramic materials and has now listed us as the designated quartz supplier.
Case Three: Japanese LED chip manufacturing enterprises
Challenge: Quartz reaction tubes used in MOCVD equipment need to reduce internal film deposition and extend the cleaning cycle.
Solution: We have developed an inner wall densification treatment process, reducing the inner surface roughness of the quartz tube to Ra≤0.1μm.
Outcome: The maintenance cycle of the customer's equipment has been extended from the original two weeks to four weeks, and the annual maintenance cost has been reduced by approximately 30%.
