POROUS TITANIUM-HYDROXYAPATITE COMPOSITE AND METHOD FOR PREPARING THE SAME

摘要

PURPOSE: A porous titanium-hydroxyapatite(ha) composite and a manufacturing method thereof are provided to prevent cell death and to enable efficient cell proliferation and cell fixation by sintering and leaching titanium and hydroxyapatite. CONSTITUTION: A manufacturing method of a porous titanium-hydroxyapatite(ha) composite comprises the following steps: mixing titanium (Ti) powder and hydroxyapatite powder; forming a composite by sintering the mixed powder; and adding the composite to a leaching solution and forming a pore by eluting the hydroxyapatite. A particle size of the titanium powder is 5-100 micro meters and the hydroxyapatite powder is 5-100 nano meters. 10-50 weight% of the hydroxyapatite powder is mixed in the titanium powder. The sintering step is processed under 10-200 MPa, at 800-1200 deg. Celsius for 2-10 minutes. The porous titanium-hydroxyapatite composite comprises micro sized pores which are connected as 3D.
