| Abstract: The porous apatite-wollastonite bioactive glass-ceramic (AW-GC) was fabricated from nano-precursor powders derived from sol-gel process, and shaped by dipping with the polymer foam. Through controlling the solid volume fraction and additives contents, the slurry was prepared by using the nano-precursor powders, then, was dipped with polymer foams for coating process, after drying and sintering, the porous AW bioactive glass-ceramic was obtained. Crystalline phase, surface morphology and microstructure of the materials were studied by means of XRD, SEM, TEM, DTA. The bioactivity of the materials was investigated in simulated body fluid (SBF). The results show that porous AW-GC has three-dimensional pored structure, high porosity, suitable macropores as well as micropores and high bioactivity. |
