Ultrasonic Spray Pyrolysis System
The ultrasonic spray pyrolysis process can be simply described as a series of physicochemical processes, such as mixing each metal salt into a precursor solution according to the stoichiometric ratio required for the preparation of composite powder, atomizing it by the atomizer, and then bringing it into the high-temperature reaction furnace by the carrier gas. In the reaction furnace, a series of physical and chemical processes, such as solvent evaporation, solute precipitation to form solid particles, particle drying, particle thermal decomposition, sintering and molding, are completed instantaneously, and finally, ultrafine powder is formed. Using ultrasonic spray pyrolysis systemtechnology, the ceramic ultrasonic transducer solution can be uniformly atomized into micron or even nanometer liquid droplets, and the atomized droplets are sent to the high-temperature reaction furnace through carrier gas for pyrolysis. The ultrasonic spray pyrolysis can produce more uniform and fine powder particles than conventional pyrolysis.

FAQ of Ultrasonic Spray Pyrolysis System
What kind of atomizer is used in ultrasonic spray pyrolysis system?
It is usually Siansonic nano aerosol generator which can generate the droplet as small as 0.5 micron. For some application, ultrasonic spray nozzle can also be used in the pyrolysis system.
How does the ultrasonic spray pyrolysis system collect the produced ultra-fine powder?
We use a unique particle collector based on high voltage electrostatic technology. It can collect the particle as small as 0.1 nanometer and the collecting ratio is higher than 95%.
What is the maximum temperature of this ultrasonic spray pyrolysis system?
Generally, the maximum heating temperature of tube furnace made of quartz is 1200°C. It can also customize with other tube material such as aluminium oxide for higher temperature.
