【 摘 要 】
Glass-ceramicsfoams prepared from glasses of the SiO2-Na2O-CaO-P2O5by replication process were obtained and characterized in terms of their chemicaland physical properties by X-ray fluorescence, X-ray diffraction, laser diffraction,thermal analysis, density, mechanical strength, microstructural and cytotoxicanalysis. The results showed that it is possible to produce glass-ceramic foamsby the replication method with optimized properties but cytotoxic analysis indicatesthat the glass-ceramic foams are not bioactive materials. Mechanical strengthvalues varying from 0.5 to 1.0 MPa and from 0.8 to 2.3 MPa were reached formean particle sizes of 10 and 6 µm, respectively.
