U-shaped tube furnace quartz tube
The U-shaped tube furnace quartz tube is a high-purity quartz glass tube designed specifically for tube furnaces. Its unique U-shaped structure is suitable for various high-temperature experiments and industrial heat treatment processes. Quartz tubes (mainly composed of SiO ₂) have excellent thermal stability, chemical inertness, and transparency, and can work stably in high temperatures (usually ≤ 1200 ° C, short-term up to 1450 ° C) and corrosive environments.
1.1 Structure and Characteristics
-U-shaped design: with open ends and a 180 ° bend in the middle for easy gas circulation and sample placement.
-High purity material: fused silica or Synthetic Quartz are used, with SiO ₂ content ≥ 99.99%.
-Temperature resistance performance:
-Long term use temperature: ≤ 1200 ° C (ordinary quartz tube) or ≤ 1450 ° C (high-purity quartz tube).
-The coefficient of thermal expansion is extremely low (5.5 × 10 ⁻⁷/° C), and it has strong thermal shock resistance.
-Chemical inertness: Acid resistant (except hydrofluoric acid), alkali resistant (stable in weak alkaline environments), suitable for corrosive atmospheres (such as Cl ₂, H ₂, etc.).
-Optical characteristics: Good transparency in the ultraviolet infrared band, suitable for photocatalytic experiments.
2. Main applications
U-shaped tube furnace quartz tubes are widely used in scientific research experiments and industrial production, with main scenarios including:
2.1 Material Heat Treatment
-High temperature sintering: synthesis of ceramics and metal oxides (such as ZnO, TiO ₂).
-Annealing process: Stress relief for semiconductor materials and glass products.
2.2 Chemical Vapor Deposition (CVD)
-Used for growing carbon nanotubes (CNTs), graphene, or semiconductor films (such as SiC, GaN).
-The U-shaped structure can optimize gas flow and improve deposition uniformity.
2.3 Catalyst research
-Activation and reduction of supported catalysts (such as Pt/C, Ni/Al ₂ O3).
-Corrosion resistance is suitable for catalytic reactions in acidic/alkaline atmospheres (such as Fischer Tropsch synthesis).
2.4 Gas Purification and Reaction
-Gas cracking: such as methane cracking to produce hydrogen.
-Corrosive gas experiment: Material testing in environments such as chlorine gas (Cl ₂) or fluorine gas (F ₂).
2.5 Optoelectronics and Energy Research
-Photocatalytic reactions (such as TiO ₂ degradation of organic compounds).
-High temperature treatment of fuel cell materials, such as SOFC electrolytes.
3. Customized services
According to different experimental requirements, U-shaped quartz tubes can provide various customized solutions:
3.1 Size customization
-Non standard pipe diameter/length: meets the requirements of special furnace bodies or samples.
-Multi port design: Add air inlet, exhaust port or thermocouple socket.
3.2 Material Upgrade
-High purity quartz (HPQ): reduces metal impurities (Fe, Al, etc.), suitable for semiconductor processes.
-Cerium doped quartz: enhances resistance to ultraviolet radiation.
3.3 Surface Treatment
-Inner wall sanding: improves gas diffusion uniformity.
-Outer wall coating: such as infrared reflective coating, to improve heating efficiency.
3.4 Accessory Integration
-Flange sealing: Paired with CF flange or O-ring, it can achieve vacuum (10 ⁻ ⊃3; Pa) or high pressure (1MPa) environment.
-Support frame: Equipped with quartz or corundum support to prevent high temperature deformation.
4. Precautions for use
1. Temperature control: To avoid local overheating (such as direct contact with flames), it is recommended to increase the temperature rate by ≤ 10 ° C/min.
2. Atmosphere limitation: Hydrofluoric acid (HF) or hot phosphoric acid can corrode quartz, and platinum tubes need to be used instead.
3. Mechanical protection: Quartz tubes have high brittleness and need to be protected against impact during installation.
4. Cleaning method: After use, organic residue can be removed by soaking in dilute nitric acid or high-temperature calcination.
The U-shaped tube furnace quartz tube has become a key component in materials science, chemical synthesis, and energy research due to its high temperature resistance, corrosion resistance, and flexible design. Through customized services such as size adjustment, multi port design, or high-purity materials, specific experimental needs can be further met. Users need to choose the appropriate specifications based on the actual process and follow the operating procedures to extend the service life.
