| Abstract: | Sodium silicate based glasses have been synthesized by melt quenching
technique. The surface reactivity of resultant glasses has been analyzed by
immersion studies in simulated body fluid solution (SBF) for different time
duration. The formation of hydroxyapatite layer has been studied through weight
change (loss/ gain) of glass sample and change in pH of SBF solution. The addition of Al2O3
instead of P2O5 in sodium silicate glasses increases the
durability of glasses in SBF solution. The optical band gap decreases with
increase of sodium oxide content with soaking
time of glass in SBF. |
