Biogenic materials like corals, which are readily available, could be used to produce bioceramic materials and
address significant advantages due to their unique structures and chemical compositions that contain Mg and Sr.
Many conversion processes has been in the past proposed. In this work, a comparison study between the
conversion of coral with orthophosphoric acid and ammonium dihydrogen phosphate was conducted. The
resultant structures and compositions were studied using XRD, ICP-MS, SEM and FTIR. The results show that
with phosphoric acid the coral was converted into mainly monetite (92%). The ammonium dihydrogen
phosphate converted approximately 76% of the coral to hydroxyapatite through solid state reactions. The two
routes proved to be effective in producing bioceramic materials from corals under moderate conditions of
temperature with a basic condition favouring the yield of hydroxyapatite. |
