Fluidized Bed CVD(FBCVD)Furnace with 2.4Mhz Ultrasonic Atomizer for Preparing Core-Shell/Nano Structure Particles - OTF-1200X-S-FBUS


Please email for lead time
Item Number: OTF-1200X-S-FBUS
Transported by LTL Freight (Truck)
OTF-1200X-S-FBUS is a UL/CSA ready Fluidized Bed Vertical Furnace with Ultrasonic atomizer for powder CVD ( FBCVD)applications. It consists a vertical positioned cylindrical heating chamber which surrounds the quartz tube with a built-in filter right in the lower middle section of the central heating zone. Its filter is a porous (15~40 microns) quartz frit that allows the controlled gas flow pass through and  float the particles on a cushion of the gas stream where the interaction between the solid and gaseous and liquid materials take place. This is an ideal tool for core-shell structure nano-powder formation.
 
SPECIFICATIONS:
Fluidized Zone



  • Ultra-high frequency (2.4Mhz) ultrasonic atomizer can deliver sub-microns droplets to the heated flowbed for the subsequent decomposition and CVD coating on powder.
  • Provides uniform distribution of the gas and solution sub-micron particles blast over the entire cross section of the tube chamber
  • Solid particles are suspended by an upward gas flowing
  • Excellent heat transfer and coating to every single suspended particle 
  • Processed materials can be discharged from the top side of the tube after the cap is been taken off

Note: The gas is passed upward through the fluidized bed at a high enough velocity to lift the particles. However, particles may be swept away from the tube chamber entirely if the velocity was set too high. Depends on the particle size, you may want to adjust the gas in pressure and flow rate until particles are lifted and move turbulently inside of the tube.

  • 110VAC, 2.4 MHz ultra-high frequency Ultrasonic Generator can generate sub-microns solution particles
  • Fluoropolymer coated liquid container and Fluoropolymer sealing gaskets
  • external Fluoropolymer optical sensor and valve for keeping the liquid level to the correct height and preventing damage to the nebulizing element, should the unit run dry.
  • Ultrasonic power programmable,0~100%, 5% increment.
  • 304 Stainless Steel T-piece (1.5'' sanitary fitting) with 1/4'' tube fitting adapters enables the use of carrier gas.
Quartz Frit

Frits with forced convection design can trap the particles within the central heating area
  • Frit: 15~40 microns porous, 22mm O.D x 4mm thick

Warning

  • Tube furnaces with quartz tube is designed for using under low positive pressure < 0.2 bars / 3 psi / 0.02 Mpa
  • The flow rate for gasses should be limited to < 200 SCCM (or 200 ml/min) for reducing thermal shocks to the tube
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
