Disclosed is an orthopedic and dental implant ceramic composition comprising hydroxyapatite and whitlockite. Said composition is prepared by blending 50 to 99.5% by weight of a crystalline hydroxyapatite and 0.5 to 50% by weight of whitlockite, and then, sintering the blend at a temperature of 900 DEG to 1,400 DEG C. Said crystalline hydroxyapatite is prepared by the solid phase reaction wherein a mixture of a calcium phosphate, having a Ca/P ratio of 1.5 to 1.67 by mole, and a stoichiometric amount or more of a calcium compound is heated at a temperature of 500 DEG to 1,000 DEG C. Said calcium compound is at least one compound selected from the group consisting of CaCO3, CaO, Ca(OH)2, CaF2, Ca(COO)2, Ca(NO3)2 and CaCl2. |
