Abstract

Plasma spheroidization of hydroxyapatite powders inevitably results in the formation of amorphous calcium phosphate. The crystallization of the amorphous phase can be thermally induced. The thermal crystallization is studied by means of differential scanning calorimetry (DSC) and X-ray diffraction (XRD). We aim to investigate the temperature at which the crystallization takes place and to have fundamental understandings about this phase transformation (i.e., activation energy and enthalpy).
