摘要：

Bioactivity and magnetic properties were investigated in glass and glass ceramics based on the SiO2-Na2O-Fe2O3-CaO-P2O5-B2O3 system to find their suitability as thermoseed for hyperthermia treatment of cancer. The effect of change in compositions on bioactivity was examined in simulated body fluids. The glass ceramic samples exhibit Na3CaSi3O8 and Na3-xFexPO4 phases. After dipping the glass ceramic samples in simulated body fluids silica hydrogel first forms, followed by an amorphous calcium phosphate layer. Magnetic and microwave resonance experiments further demonstrate the potential of these glass ceramics for possible use in hyperthermia. (C) 1999 Kluwer Academic Publishers.
