摘要：
The present invention provides a method for stabilizing fine particles of calcium phosphates without lowering their solid phase forming activity.It is possible to stabilize the fine particles of calcium phosphates by stopping the growth of the fine particles formed in an aqueous solution supersaturated with respect to calcium phosphates. More specifically, the fine particles of calcium phosphates were stabilized by lowering the inorganic ion concentration of a fine-particle-forming solution containing fine particles of calcium phosphates by dialysis, ion exchange, dilution, or the like, or by separating the fine particles of calcium phosphates from the fine-particle-forming solution by filtration, centrifuging, or the like.
