Whitlockite and method for manufacturing the same

A whitlockite, wherein the whitlockite is manufactured by a manufacturing method comprising:

• adding, to water, a calcium ion supplying material and a cation supplying material containing a cation (X) other than a calcium ion to prepare a cation aqueous solution;
• adding a phosphoric acid supplying material to the cation aqueous solution;
• and
• aging the cation aqueous solution including the phosphoric acid supplying material,
• wherein a temperature of the water is equal to or lower than a boiling point,
• wherein the phosphoric acid supplying material is added in a dropwise manner,
• wherein a pH of the cation aqueous solution is gradually decreased depending on addition of the phosphoric acid supplying material, and the cation aqueous solution including the phosphoric acid supplying material added thereto is aged inan acidic environment.
