Abstract

-tricalcium phosphate( -TCP) is an important biomaterial with good biocompatibility. The study was concentrated on the microstructure and performance of Mg-substituted -TCP porous ceramics. The 6mol.% Mg-doped powders were fabricated by the method of gel-sol combustion with raw materials of Ca(NO3)2, PBTC and Mg(NO3)2. Mg-substituted -TCP porous ceramics were obtained by molded-pressing with the foaming agent and the binder before calcined at 1000°C. The mechanical properties, microstructure, immersion performance had been evaluated by means of mechanical testing machine, X-ray diffraction, scanning electron microscopy with EDS and immersion test. The compressive test showed that the compressive strength of Mg-doped porous ceramics increased 10.5% from 5.92MPa to 6.54MPa compared with the pure porous scaffolds. The SEM Images demonstrated that the porosity of ceramic was about 65%, the size of interconnect holes were ranging from 50 to 200 m. Immersion test indicated that the Mg-substituted improved the performance of degradation apparently.
