Formation of hydroxyapatite crystals from octacalcium phosphate with incorporated succinate ion under hydrothermal conditions

Abstract

Transformation of octacalcium phosphate (OCP) with incorporated succinate ion to hydroxyapatite (HAp) under hydrothermal conditions was investigated herein. Plate-shaped OCP with incorporated succinate ion was transformed to HAp composed of laminated thin plate-shaped crystals, confirmed by morphological observations and X-ray diffraction analysis. The organically modified OCP is useful as the precursor for HAp crystals with unique nanostructures.
