System Structure
|
• Aerosol Generation: 1.7 MHz Ultrasonic Enhanced Bubbler can "evaporate" catalyst liquid with
literally no heat generated. A stainless steel liquid collector connects inline with the ultrasonic bubble
can prevent condensing liquid from streaming into the furnace tube chamber. - • Thermal Decomposition: three-zone ( 900mm length ) tube furnace can be heated up to 1200C
maximum to pass the droplets flux across the temperature and atmosphere regulated firing zone,
chemical, and physical conversion processes proceed. - • Nanopowder Collection: 30KV electrostatic precipitator (700 ml ) can effectively collect nano-size
particles from the carrier gas flow - • The furnace can be tilted to avoid liquid flow back atomizing tank

The speed range for the liquid injection pump is 0.004 ml/min - 70
ml/min - • A floating flow meter is included to control the carrier gas flow rate
within 0-200 SCCM. - • vA mass flow controller (MFC) is optional to precisely control the
flow rate.

Application Notes
   |
• 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.- • Please tilt furnace in 10 - 15 degrees to avoid liquid back to
atomizing bubbler - • It is the customer responsibility to achieve the ideal parameter for
particle size. Usually, the liquid injection rate and carrier gas flow
rate has an important influence on particle size. - • The SEM picture left is SnO2 particle ( ~ 500 nm - 5 um) generated
by the equipment via Stannic chloride solution at 800oC
