Abstract
Octacalcium phosphate (OCP) crystal is composed of apatite having general formula Ca5(PO4)3X, where X=F, Cl or OH and they are key component of bone and teeth, where its hydrated layers producing thin plate-shaped hydroxyapatite (HAP) nanocrystals. Here, we have been reported the synthesis of sample of HAP nanocystals as CALPHOS or CONTROL and SUC or Suc-20 under hydrothermal condition from succinic acid’s ion based OCP at 180 0C for 3hours. During incorporating of succinate ions in OCP crystals the hydrogen phosphate (HPO42-) ions in the hydrated layers of OCP are being substituted by succinate ions. Since, HAP crystal system is hexagonal and it characterized by using of SEM, XRD and FTIR technique. The crystallite size of HAP crystals are as perpendicular to the (100) plane which can calculate by using as D100 = Kλ/(β cos θ) equation of Scherrer.
