Large size 25 mm 1000-1200 ° C tube furnace quartz tube
The large-sized 25mm quartz tube is a core component designed specifically for high temperature environments of 1000-1200 ° C. It is made of high-purity synthetic quartz glass and has excellent high temperature resistance, chemical stability, and transparency. Its specifications include an outer diameter of 25 mm, an inner diameter of 20-23 mm (customizable), and a length of 600-1000 mm, which can meet the needs of precision laboratory experiments and also adapt to batch processing scenarios in industrial production.
Core performance parameters
Temperature tolerance range: Continuous working temperature of 1000 ° C, short-term tolerance of 1200 ° C (≤ 2 hours), suitable for the maximum working temperature requirements of the tubular furnace.
Thermal shock stability: supports rapid heating from room temperature to 1200 ° C (such as heating up within 15 minutes), reducing experimental waiting time.
Transparency: Quartz glass has a transmittance of over 90% from ultraviolet to visible light, allowing for real-time observation of the phase transition process of the sample (such as directional growth of zirconia crystals).
Vacuum compatibility: When used in combination with mechanical pumps and molecular pumps, the vacuum degree can reach 10 ⁻⁵ Torr, effectively isolating oxygen and impurity interference.
Structural advantages
Sealed design: equipped with stainless steel flanges, integrated mechanical pressure gauges, needle valves, and protective gas interfaces, supporting rapid vacuum pumping (reaching working vacuum degree within 8 minutes).
Safety protection: Built in over temperature alarm, thermocouple protection, and air pressure monitoring system. When the air pressure inside the furnace tube exceeds 0.02 MPa, it will automatically release pressure to prevent quartz tube rupture.
Energy saving design: Adopting high-purity alumina fiber furnace, the surface temperature is reduced by 30%, the energy consumption of the empty furnace is reduced by 50%, and the equipment life is extended.
Application field
The large-sized 25mm quartz tube is widely used in the following scenarios due to its high performance and flexibility:
1. Semiconductor material processing
Problem solving: Traditional metal furnace tubes are prone to releasing impurities at high temperatures, causing fluctuations in silicon wafer resistivity exceeding ± 5%. The purity of the quartz tube reaches 99.99%, and the resistivity error can be controlled within ± 3%.
Typical case: In the annealing process of silicon carbide chips, the carrier mobility is increased by 12% through vacuum environment and precise temperature control (± 1 ° C).
2. New ceramic sintering
Problem solving: Powdered ceramic materials are prone to lattice defects during sintering due to oxidation. The vacuum environment of quartz tube can promote the discharge of pores and increase the density of sintered body.
Typical case: In the sintering of zirconia ceramics, researchers observed crystal growth through side windows and optimized the process, resulting in a 20% increase in product fracture toughness.
3. Synthesis of nanomaterials
Problem solving: When CVD method is used to produce graphene, the traditional furnace tube temperature uniformity is poor (± 10 ° C), resulting in batch consistency below 80%. The quartz tube combined with PID coupling algorithm reduces temperature fluctuations to ± 2 ° C and improves batch consistency to 93%.
Typical case: In the preparation of molybdenum disulfide thin films, defect formation energy was reduced by 0.7 eV through a laser assisted heating module (introduced with a 532nm laser).
4. Research and development of new energy battery materials
Problem solving: The sintering of the positive electrode material needs to be maintained at 1200 ° C for 12 hours. Traditional furnace tubes have high energy consumption and large temperature fluctuations. The energy-saving design of quartz tubes can reduce electricity costs by 30%, while the temperature field uniformity (± 5 ° C) meets the synthesis requirements of high nickel ternary materials.
5. Manufacturing of optical components
Problem solving: Avoid metal contamination during annealing of quartz glass lenses. The chemical stability of the quartz tube ensures that the surface roughness Ra of the lens is ≤ 0.5 nm, meeting the optical grade standard.
Customized service
To meet diverse needs, the following customization options are provided:
1. Size customization
Diameter range: 25 mm to 100 mm (e.g. 50/44 × 1000 mm, 80/74 × 1000 mm).
Length extension: Supports up to 2000 mm furnace tubes, suitable for the 1500 mm constant temperature zone requirements of six temperature zone tube furnaces.
2. Interface and flange upgrade
Quick disassembly and installation of flanges: supports furnace tube replacement within 1 minute, improving experimental efficiency.
Observation window flange: Integrated quartz window for real-time monitoring of sample status.
Water cooled flange: suitable for long-term high-temperature experiments, reducing the risk of flange thermal deformation.
3. Atmosphere control system
Gas flow regulation: Optional Mass Flow Controller (MFC) with an accuracy of 0.1 SCCM, supporting the introduction of gases such as nitrogen, argon, and hydrogen.
Corrosive gas treatment: Provides polytetrafluoroethylene (PTFE) flange options, resistant to acidic gases such as HF and HCl.
4. Customization of temperature control program
Multi stage heating: Supports 30 stage program temperature control, with adjustable heating rate (≤ 20 ° C/min), constant temperature time, and cooling curve.
Intelligent algorithm: integrates temperature vacuum coupling function, automatically adjusts heating power to compensate for gas heat release effect.
