| Abstract: Two kinds of macroporous bioglasses were prepared via sol suspension and precipitate using Polyethylene Glycol particles as pore former. The samples were characterized using scanning electron microscopy (SEM), BET, X-ray diffraction (XRD), Intrusion Mercury Porosimetry, mechanical strength test and in vitro bioactivity test. These glasses exhibited a hierarchical structure with interconnected macropores (10～300 μm) and mesopores (2～50 nm) framework. In vitro tests showed that the samples had excellent bioactivity. The samples derived from precipitate showed better macroporous structure and much higher mechanical strength. |
