Abstract: PURPOSE: A process of preparing a ceramic composite for easy control of biosolubility by improving sinterability of a hydroxyapatite and tricalcium phosphate complex is provided which increases strength of the ceramic composite by 3 times while obtaining high density ceramic. Thus obtained ceramic composite can be applied to an artificial tooth and bone-graft material. CONSTITUTION: About 0.2 to 10% by weight of a magnesium salt is added to a complex of hydroxyapatite and tricalcium phosphate in a ratio of 5:95 to 80:20. The magnesium salt comprises one or more selected from the group consisting of magnesium nitrate, magnesium chloride, magnesium oxide, magnesium hydroxide and magnesium carbonate. In a case of synthesizing the hydroxyapatite and tricalcium phosphate, a magnesium is added instead of a calcium salt and then sintered.
