The bioactive glasses 58S was first prepared using sol-gel technique and the 45S5 bioactive glass was prepared through melting method. The above bioactive glasses were then grounded into fine powders, and each of the glass powders and their mixtures was doped with the porogen in certain ratios respectively. The bioactive porous materials were finally produced through sintering. We investigated the microstructure, surface morphologies, bending strength and bioactivity of the porous materials via in vitro method combined with DTA, SEM and FTIR techniques. The results show that the porous material made from the 58S and 45S5 mixture possesses the best bioactivity and bio-mineralization function among all samples, thus is a very promising bioactive material for bone defects filling or bone tissue engineering scaffolds.
