Effect of Calcium Carbonate in the Studies and Synthesis of Hydroxyapatite
Abstract: Hydroxyapatite (HA) has been the focus of biomaterials research as it is highly biocompatible and bioresorbable ceramic with relatively simple processing. Hydroxyapatite (HA) also helps in restoration of damaged or deceased bones. Several methods are proposed in preparation of HA from aqueous solution. In this paper, HA is prepared by direct precipitation reaction method using orthophosphoric acid (H3PO4) and calcium hydroxide Ca (OH)2 as precursors for various Ca / P molar ratio. The prepared HA was subjected to XRD and FTIR where the analysis reveals the presence of (CHA) Carbonate Hydroxyapatite which has excellent resorbable property. The present study substantiates that the fabricated material is of nanoscale. The variations in the amount of CHA for different Ca/P ratio were observed.
