The object of the present invention is to provide a method for producing carbonates capable of effectively and easily forming carbonates shaped to have an orientational birefringence and an aspect ratio greater than 1 as well as capable of controlling the particle size. For this end, it is a method of which a metallic ion source containing at least one selected from Sr2+ ions, Ca2+ ions, Ba2+ ions, Zn2+ ions, and Pb2+ with a carbonate source in a solution to thereby produce carbonates shaped to have an aspect ratio greater than 1, and the method include increasing the number of carbonate particles and increasing the volume of carbonate particles. |
