Abstract

Abstract : The transformation product of amorphous calcium phosphate without inhibitors at room temperature is monoclinic HAp rather than the more common hexagonal HAp. Abstract : Monoclinic nano-hydroxylapatite (nHAp) rarely forms at room temperatures, especially from amorphous calcium phosphate (ACP) precursors. We developed a method to synthesise monoclinic nHAp from ACP without crystallisation inhibitors at 25 °C. Additionally, Raman spectroscopy was identified as a reliable technique for observing the crystallisation process.
