Abstract: Nano bio composites have emerged recently as an efficient strategy to upgrade the structural and functional properties of synthetic bone grafts Bioactive ceramics have attracted wide attention because of their biocompatibility Nanohydroxyapatite is considered the most suitable material for bone replacement as it closely mimics the mineral part of the bone tissue The applications as long bone substitute and load bearing scaffolds are held up by the inherent low fracture toughness exhibited by nHAp So it is necessary to develop composite materials exhibiting improved biomechanical features And it is indispensable to characterize nano hydroxyapatite before it is mixed with the organic phase to form a nano biocomposite that mimics the natural bone In this endeavor the synthesis of nano particle hydroxyapatite powders by the wet chemical method is reported This method incorporates a freeze drying step followed by calcination at 600 C and a slurry of precipitated material of nHAp is allowed to dry in air The materials were characterized by analytical methods including FT IR XRD TG DTA and SEM FT IR studies confirm the presence of hydroxyapatite with weak hydroxyl peaks in calcined nHAp and XRD patterns show biphasic nature of nHAp with tricalcium phosphate newline
