(57) [Summary] [Object] An object of the present invention is to provide an inexpensive and efficient method for producing plate-like calcium carbonate having good dispersibility, which can be used as a filler and a coating agent for papermaking, resin, paint, rubber and the like. Is to provide. According to the method of the present invention, carbon dioxide is produced under the condition of producing basic calcium carbonate in the process of producing calcium carbonate by introducing carbon dioxide gas into an aqueous suspension of calcium hydroxide, and in the presence of an organic amine compound. It is a method for producing plate-like calcium carbonate, which is characterized by carrying out a chemical reaction. |
