摘要：

Na2O-CaO-TiO2-P2O5 glass-ceramics containing Nasicon-type crystals were found to have silver-ion exchangeability. The Nasicon-type phase contains Ca2+ and N+ ions which are located in two different sites of the conduction channels: the Na+ ions with high mobility can be exchanged easily with Ag+ ions in aqueous solution. The Ag+-ion-exchanged glass-ceramics showed excellent bacteriostatic activity and a relatively high strength of 160 MPa in bending.
