K. Senthilarasan ^[2] | P. Sakthivel ^[4]

Abstract: In this present study, nano particles with two phases Hydroxyapatite and Gum Arabic (nHAp/GA) were prepared using modified wet chemical method. Hydroxyapatite (HAp) is a biocompatible ceramic that is widely used in a number of biomedical applications and devices. Due to its close similarity with natural bone matrix in nanometer scale, research is carried out to study its reaction with biopolymer at this scale. HAp and mineral phase found in the natural bone matrix, Gum Arabic (GA), a kind of plant-polysaccharides, were used to improve the property of artificial bone matrix and widely used for pharmaceuticals purposes. These composite were Characterized by FT-IR, X-ray diffraction, Transmission electron microscope techniques and thermal analysis. The crystallite size, lattice parameters, specific surface area, volume density, microstrain, u parameter and dislocation density were also measured by using XRD data.
