In Vitro Bioactivity Evaluation of Flourapatite Nanopowder Produced by Mechanical Alloying Method

Flourapatite (FA) nanopowder was synthesized by mechanical alloying (MA) method. In vitro test was performed by immersion of nanopowder in Kokubo's SBF for a maximum period of 4 weeks. Synthesized nanopowder was characterized using X-ray diffraction analysis (XRD) and Transmission electron microscopy (TEM). The changes of pH of the SBF were measured at pre-determined time intervals using a pH meter. The calcium and phosphorous ions concentrations of SBF were determined using ICP-OES analysis. The In vitro test indicated the precipitation of bone-like apatite on the surface of soaked powders during soaking in the SBF
