Abstract
The present invention aims to provide techniques for efficiently synthesizing inorganic microparticles. According to the present invention, inorganic carbonate microparticles can be synthesized by generating ultrafine bubbles containing carbonic acid gas by injecting a gas containing carbonic acid gas and a liquid into a reaction vessel through a nozzle to deposit an inorganic carbonate having an average primary particle size of 300 nm or less in the presence of the ultrafine bubbles.
