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.
