Development and Study CaO-B2O3-P2O5 Glass System

Glasses in the system 20wt%boric oxide and 80wt % [CaO-P2O5] have been prepared by rapid quenching technic from the melts at high temperature. Ca/P molar ratios have been varied 1.65, 1.67 and 1.69. The amorphous nature of glass powder was confirmed by XRD analysis. Thermal and crystallization behavior were carried out by DSC analysis. The Sintering behavior and mechanical properties were investigated by dilatometry and biaxial flexural and diametral strength testing methods. The bioactivity of glass powder and glass scaffold were investigated after immersion in the simulated body fluid (SBF) for 1, 7, 14 &21 at 37.80c. Microstructural study has been analyzed using field emission scanning electron microscopy (FESEM). X-ray diffraction patterns clearly showed the deposition of Calium phosphate which is amorphous in natur
