Structural, optical and bioactive properties of calcium borosilicate glasses

Abstract
Abstract Glass of composition 40SiO 2 –20B 2 O 3 –30CaO–10M 2 O 3 (M = Al, Cr, Y and La) were prepared by the splat quenching technique to investigate the effect of M 2 O 3 on their bioactivity, structural and optical properties. Y 2 O 3 and Cr 2 O 3 containing glasses formed a crystalline hydroxyapatite (HA) layer after dipping in simulating body fluid (SBF) for 25 days. On the other hand, HA layer could not form in Al 2 O 3 and La 2 O 3 glasses. However, during soaking in SBF solution, these glasses exhibit higher dissolution rate, lower density and increased optical band gap as compared to unsoaked glasses. Their oxygen molar volume was also higher than for Y 2 O 3 and Cr 2 O 3 glasses. The change in composition affects the cross-link formation in the glass matrix and finally its durability and bioactivity in SBF. The results show that M 2 O 3 plays an important role in controlling chemical durability and bioactivity of the glasses.
