OTF1200XIII-PGEP Ultrasonic Spray Pyrolysis Furnace with 3-Zone 1200°C Tube Furnace and Electrostatic Nanopowder Collector for Nanoparticle Synthesis and AACVD
The OTF1200XIII-PGEP system is engineered to facilitate advanced nanoparticle synthesis through ultrasonic spray pyrolysis, enabling precise control over particle size, morphology, and microstructure. It is especially suited for producing nano- and core-shell structured particles and supports aerosol-assisted chemical vapor deposition (AACVD) processes. This system integrates three critical stages: aerosol generation, thermal decomposition, and nanopowder collection, streamlining nanoparticle fabrication workflows.
Liquid precursor droplets are atomized by a 1.7 MHz ultrasonic enhanced bubbler, which operates without thermal evaporation, producing a fine aerosol. The aerosol passes through a 900 mm long three-zone tube furnace with independently controlled zones, capable of reaching a maximum temperature of 1200°C for short durations and continuous operation at 1100°C. Thermal and chemical reactions within the furnace convert the aerosol into nanoparticles. The system’s furnace can be tilted to prevent liquid backflow into the atomizing tank, enhancing operational reliability.
