Round bottom transparent quartz tube is a special quartz product made of high-purity silicon dioxide (SiO ₂ ≥ 99.99%) through high-temperature melting process. With its unique round bottom design, excellent optical transparency, outstanding thermal stability and chemical inertness, it has become a core material component in laboratories, semiconductors, optoelectronics and high-end industrial fields.
Core product advantages
1. Ultimate material performance
-High purity and transparency: Made from natural crystal or high-purity silica sand raw materials, with a light transmittance of over 93% (UV to IR band), no bubbles, and uniform stripes.
-Excellent temperature resistance: softening point up to 1730 ℃, long-term use temperature of 1200 ℃, no explosion during sudden cooling and heating.
-Chemical inertness: Resistant to almost all acids, solvents, and metal melts except hydrofluoric acid and hot phosphoric acid.
-Low coefficient of expansion: The thermal expansion coefficient is only 5.5 × 10 ⁻⁷/℃, and the dimensional stability is excellent.
2. Precision machining technology
-Round bottom integrated molding technology, seamless and stress free
-Precision polishing of inner and outer surfaces to reduce pollutant adsorption
-Dimensional accuracy control: diameter tolerance ± 0.1mm, wall thickness uniformity>95%
3. Customized production capacity
-Diameter range: 10mm to 300mm
-Length range: 100mm to 2000mm
-Support customized special designs such as openings, branch pipes, flange connections, etc
-Secondary processing such as coating and coating can be carried out according to requirements
Main application areas
Laboratory and Research
-High temperature reaction vessel, vacuum pipe fittings
-Spectral analysis sample pool, UV sterilizer
-Single crystal growth furnace tube, diffusion furnace tube
Semiconductors and Optoelectronics
-Wafer carrier, diffusion tube, cleaning tank
-LED/MOCVD reaction tube, photovoltaic coating tube
-Fiber preform processing
Industrial and Medical
-High temperature observation window, industrial furnace sight glass
-Medical sterilization equipment, laser casing
-Chemical process monitoring pipe fittings
The key problem we are solving
1. Replace restricted materials
Replace ordinary glass, ceramic or stainless steel fittings to solve their failure problems in high temperature and strong corrosive environments.
2. Improve process stability
Provide a clean environment with extremely low impurity content for the semiconductor and photovoltaic industries, reducing product defect rates.
3. Reduce overall costs
Longer service life (usually 3-5 times that of ordinary materials) reduces replacement frequency and downtime losses.
4. Accelerate the research and development process
Provide specialized pipe fittings that can be customized according to experimental needs for scientific research institutions, shortening the procurement cycle.
