| Popis: | The composites of different compositions of 70Sr–HA.xZn (30-x)Si were prepared by two different methods: conventional sintering and microwave sintering. XRD characterized the prepared samples for phase identification, FTIR and Raman for functional groups, SEM for microstructure, hardness for mechanical properties. X-ray diffraction studies showed that multiple phases were present in all the samples. The values of density and hardness of apatite composite samples sintered by microwave processing were higher than the apatite composite samples sintered by the conventional method. Microwave sintered products showed more uniform and higher grain growth in comparison to conventionally sintered products. In vitro bioactivity of the synthesized composites was assessed by the SBF immersion method. It was observed that the bioactivity of the microwave processed apatite was better than the conventionally processed apatite. |
