摘要：
Glass-ceramics in the composition field of CaO-K2O-MgO-Na2O-P2O5 can be produced based on the main crystalline phase Ca2KNa(PO4)(2). The degradation rate depends on the whole composition, i.e. the crystalline phases as well as the residual glass-phase. The degradation rate of the two investigated glass-ceramics was higher as in beta-tricalciumphosphate (beta-TCP) and was mainly due to passive leaching processes, especially in GB18. Both materials exhibited bone-bonding properties and allowed at least for partial guided bone regeneration during degradation.
