1. A method for preparing a whitlockite crystal, the method comprising:
a first process of adding a first solution containing phosphate ion to a container including a second solution containing calcium ion and magnesium ion, wherein the first solution containing phosphate ion is added to the container by pouring manner;
a second process of adding, to the container, a third solution containing magnesium ion and a fourth solution containing phosphate ion, wherein the fourth solution containing phosphate ion is added to the container by pouring manner; and
a third process of aging the solution in the container such that the whitlockite crystal is generated.
