Title:
METHOD FOR PRODUCING INORGANIC CARBONATE
Document Type and Number:
WIPO Patent Application WO/2018/047749
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a technique for efficiently synthesizing fine inorganic particles. According to the present invention, fine particles of an inorganic carbonate are able to be synthesized by producing ultrafine bubbles containing a carbon dioxide gas by spraying a liquid and a gas containing a carbon dioxide gas into a reaction container through a nozzle and by having an inorganic carbonate, which has an average primary particle diameter of 300 nm or less, precipitate in the presence of these ultrafine bubbles.
