SYNTHESIS AND CHARACTERIZATION OF HYDROXYAPATITE WITH TAMARIND KERNEL POWDER (BIO - POLYMER) FOR BIOMEDICAL APPLICATIONS

Hydroxyapatite which composes inorganic phase is one of the biomaterials for artificial bone and reconstruction of broken or disordered bones. It has great biocompatibility. Polysaccharide based biomaterials are an emerging class in several biomedical field such as tissue regeneration, particularly in drug delivery device. Tamarind kernel powder is used as a source of carbohydrate for the adhesive or binding agent in many of t he pharmaceutical products. There fore synthesis of Nano hydroxyapatite with tamarind kernel powder (nHAp/TKP) has been carried out to study its characterization in biomedical application. Chemical structures and functional groups of the synthesized compos ite have been examined by the Fourier transform infrared technique and x - ray diffraction. Composite morphology is determined using Transmission electron microscopy. Thermal stability was done by thermo gravimetric analysis(TGA). Crystallite size, fraction of crystallinity, surface area, microstrain, dislocation density are calculated using XRD data. The results confirms the presence of the nano particle in the composite. Nanosized composite have more number of properties such as higher specific surface are a, improved strength , hardness and thermal stability. The lattice parameter and unit cell volume are matched with JCPDS card no.09 - 0432
