SEM image of transformed succinate ion mediated OCP to hexagonal HAP Nanocrystals

Abstract

In formation of laminated thin plate-shaped hydroxyapatite (HAP) nanocrystals from succinate ion based plate-shaped octacalcium phosphate (OCP) under hydrothermal condition which are performed at 180 0C for 3hour. The morphological observation of nanocrystals have been characterized by scanning electron microscope (SEM) and other using patterns as XRD, FTIR technique. The magnifying SEM images of synthesized samples are indicates the dark line observed at the centre of Suc-20 crystals during hydrothermally, which can attributed to the gap between two thin plate crystals, likely, hexagonal HAP nanocrystals generated from organically incorporated OCP by phase transformation.
