The large-diameter furnace quartz tube is one of our company's core technological products, designed and manufactured specifically for high-temperature industrial applications. Using high-purity natural quartz sand, processed by electric melting technology, it has excellent heat resistance, chemical stability, and optical transparency. The conventional diameter range can reach 200mm-600mm, supporting customization of larger sizes. The wall thickness uniformity error is controlled within ± 0.5mm, meeting the needs of high-end industrial applications.
Core product advantages
1. Excellent material performance
-Ultra high purity: SiO ₂ content ≥ 99.99%, key impurity content (Al, Fe, Na, etc.) below 5ppm
-Excellent thermal stability: softening point up to 1730 ℃, continuous use temperature of 1200 ℃, short-term temperature resistance limit of 1650 ℃
-Low thermal expansion coefficient: 5.5 × 10 ⁻⁷/℃, excellent thermal shock resistance, able to withstand rapid temperature changes
-Excellent optical properties: maintaining high transmittance in the ultraviolet to infrared wavelength range (170nm-2500nm)
2. Precision manufacturing process
-Advanced molding technology: using a combination of electric melting and gas refining processes to ensure no bubbles or stripes
-Accurate size control: diameter tolerance ± 0.5%, ellipticity ≤ 0.3%, straightness ≤ 0.1mm/m
-Surface treatment process: optional polishing, sandblasting, pickling and other treatments to meet the needs of different application scenarios
-Quality inspection system: Each batch of products undergoes 12 tests including spectral analysis, size measurement, and pressure testing
Main application areas
Semiconductor Manufacturing
-Wafer heat treatment tube, diffusion tube, oxidation tube
-CVD and LPCVD reaction chamber tubes
-Observation window of monocrystalline silicon growth furnace
photovoltaic industry
-Polycrystalline silicon ingot furnace thermal field component
-Solar cell sintering furnace tube
-Photovoltaic material heat treatment equipment
Optics and Illumination
-High temperature halogen lamp, xenon lamp cover
-Laser optical cavity
-Special lighting equipment protection tube
Chemical Engineering and Laboratory
-High temperature corrosive medium reaction tube
-Analysis instrument observation window
-Special atmosphere protection tube
The key problems we can solve
1. Material failure under high temperature environment
Ordinary quartz tubes are prone to crystallization and deformation problems when used for a long time above 1200 ℃. Our product has a special formula and annealing process that significantly delays the crystallization process, extending its service life by 40-70% compared to conventional products.
2. Stability challenges of large-sized specifications
Quartz tubes with a diameter exceeding 300mm are susceptible to self weight deformation. We use segmented temperature controlled annealing technology and specialized support molds to ensure that large-sized products maintain shape stability at high temperatures.
3. Customization requirements for special applications
We provide comprehensive customized services from material ratios, size specifications to functional coatings to meet the special process requirements of customers in different industries.
Customized service capability
1. Size customization
-Diameter range: 200mm-1000mm (conventional), supporting larger size requirements
-Length: Up to 3000mm, supports segmented splicing scheme
-Wall thickness: 3mm-30mm, optimized design according to application requirements
2. Function customization
-Coating treatment: inner wall anti fouling coating, outer wall infrared reflective coating
-Structural design: Integration of accessories such as flange interfaces, observation windows, sampling ports, etc
-Special treatment: UV transparency enhancement, infrared cutoff and other optical characteristic adjustments
Customer Application Cases
Case 1: European semiconductor equipment manufacturer
Challenge: An ultra long quartz tube with a diameter of 480mm and a length of 2500mm is required for the new wafer annealing furnace, with a deformation of less than 0.1% at high temperatures and a service life of no less than 18 months.
Solution: We have developed a low crystallization quartz material with a special formula, optimized the annealing curve, and adopted a segmented support manufacturing process. The product fully meets the size and performance requirements.
Result: Customer feedback shows that the actual service life of the product has reached 22 months, which is 50% longer than the original supplier's product. It has been continuously purchased for 3 years, with a cumulative order of over 200 units.
Case 2: American Solar Energy Research Institute
Challenge: The observation window of the polycrystalline silicon ingot furnace requires a hemispherical quartz cover with a diameter of 350mm and a thickness of 15mm, which must have excellent infrared transmittance and thermal shock resistance.
Solution: We use the gas refining method for one-time molding technology, combined with a special annealing process, to develop hemispherical products that meet optical and thermal requirements.
Result: The product has been successfully applied to the research and development of a new type of ingot furnace, with an infrared transmittance increase of 15% and over 500 thermal shock cycles without damage.
Case Three: Japanese Special Lighting Enterprise
Challenge: The new high-temperature halogen lamp requires a quartz protective tube with a diameter of 280mm, and the inner wall needs to be coated with a special anti sodium penetration coating, with a working temperature of 1400 ℃.
Solution: We apply our independently developed alumina based composite coating on the inner wall of the quartz tube, effectively preventing sodium vapor penetration and extending its service life.
Result: The lifespan of the lamp tube has been increased from 800 hours to 2000 hours, and the customer has listed our company as a first tier supplier.
