Use of bone ash as source of CaO and P2O5 for the formation of bioactive glass-ceramic
Abstract
In this paper, we present the use of bone ash as source of CaO and P2O5 for the formation of bioactive glass-ceramics instead of using analytical grade reagents. Scanning electron microscope (SEM) micrographs of the sample soaked in simulated body fluid (SBF) for three days revealed the start of the formation of hydroxyl-carbonate-apatite (HCA) layer while sample soaked for six days showed fully developed HCA layer. Also, the measured calcium-phosphate (Ca/P) ratio using the energy dispersive xray (EDX) results of the formed layer agrees to that of the theoretical value of analytical grade bioactive glass ceramic. These suggest the biocompatibility of bone ash and therefore can be used as possible CaO and P2O5 substitute in forming bioactive glass-ceramics.
