Ah&rat--The fracture of bioactive glass-ceramics was determined in kerosene and distilled water using short bar specimens with chevron notches. By using the stable crack growth technique, an inelastic phenomenon was observed on the diagram of load versus load-point displacement. From these results,
A new bioactive glass-ceramic with a nominal composition of CaO (54.5), MgO (6.0), SiO2 (32.8), P2Os (6.1) and CaF 2 (0.6), by weight ratio, has been developed. The crystalline phases termed hydroxyfluoroxyapatite, akermanite, and wollastonite were found to be present simultaneously at a temperature
