Abstract
fabricated by pressureless sintering process. The effect of BG on the sintering ability and mechanical strength of the ceramics, and the adhesion and proliferation of osteoblasts were investigated. The results showed that the optimum amount of BG was 20wt.% and the samples sintered at 1100oC for 5h revealed a bending strength of 172 MPa, which was approximately 2-times higher than that of the pure CaSiO3 ceramics. The cell experiments showed that BG reinforced CaSiO3 ceramics supported osteoblast adhesion and possessed higher proliferation than that of the pure CaSiO3 ceramics, which indicated excellent biocompatibility. Our results suggested that BG reinforced CaSiO3 ceramics could be potential candidates as bioactive bone implant materials.
