METHOD FOR PRODUCING FLUORAPATITE AND METHOD FOR PRODUCING FLUORAPATITE PARTICULATE

摘要

PROBLEM TO BE SOLVED: To provide a fluorapatite production method for obtaining fluorapatite having high purity and high crystallinity with high productivity, and a method for producing fluorapatite particulates suitable for coating use.SOLUTION: In a fluorapatite production method, a reaction is carried out by mixing an aqueous solution containing a calcium salt with an aqueous solution containing a phosphate and a fluorine salt, and the reaction is carried out by keeping the pH of a reaction system at 5.5 or less.
