Abstract
Octacalcium phosphate according an embodiment is prepared by a process including preparing a calcium phosphate solution, controlling an initial pH by controlling a pH of the calcium phosphate solution to a range from 5 to 6 using an acidic solution, heating the calcium phosphate solution of which the initial pH is controlled to a temperature ranging from 60° C. to 90° C., adding a heterogeneous seed comprising at least one selected from among octacalcium phosphate and dicalcium phosphate dihydrate to the heated calcium phosphate solution, after adding the heterogeneous seed, adjusting a terminal pH by controlling the pH of the heated calcium phosphate solution to which the heterogeneous seed is added to a range from 5 to 6.
