[0002] Ultrasonic spray pyrolysis uses ultrasonic waves to strike a liquid to generate mist at the edge of the water column, and a carrier gas is used to transport the mist to a reaction furnace. It is very suitable for preparing nano powders with a spherical hollow structure, and has the advantages of batch production and low cost. However, most existing ultrasonic spray pyrolysis devices use a tube furnace or a vertical furnace (the atomizing gas flows from top to bottom) for heating.
