Description
Ultrasonic Spray Pyrolysis (USP) is a novel material preparation technology that utilizes ultrasonic atomization to convert liquid precursors into micron-sized droplets. These droplets are then subjected to rapid drying, decomposition, and sintering in a high-temperature reaction zone, thereby enabling the production of powders, films, nanomaterials, or functional particles.
The basic process is:
Pre-catalyst solution → Ultrasonic atomization → Tiny droplets → High-temperature pyrolysis → Solid particles collection
The ultrasonic nebulizer generates uniform and fine liquid droplets, and the size of these droplets can usually be controlled within the range of:
1–10 micrometers range
After entering the high-temperature furnace:
The solvent evaporates rapidly
The precursor undergoes thermal decomposition
Forming spherical particles or nanomaterials
Finally, a material with uniform particle size and high purity was obtained.
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 atomization technology, the 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. Ultrasonic spray pyrolysis can produce more uniform and fine powder particles than conventional pyrolysis.
