METHOD FOR PRODUCING CALCIUM HYDROGEN PHOSPHATE FINE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide calcium hydrogen phosphate fine particles having excellent moldability.SOLUTION: A method of producing calcium hydrogen phosphate fine particles represented by CaHPOnHO (n shows 0≤n≤0.5) from tribasic calcium phosphate comprises the steps of: (1) adding phosphoric acid to a mixture comprising tribasic calcium phosphate and a solvent; and (2) heat-treating the mixture to which the phosphoric acid is added.
