Abstract

Biomaterials were derived from nature and also it can be synthesized by chemical processes which can be utilized as metallic components, ceramics or composite materials. Nano Hydroxyapatite [n-HAp], a milky white coloured powder with calcium and phosphate ions stoichiometric ratio is 1.67. It was mainly used as bone and teeth fillers. The n-HAp [Ca10 (PO4)6(OH)2] was prepared by sol-gel method, as it is known to be a simple economic technique which suits for industrial or large scale production.During precipitation, the grain growth may occur. In order to avoid this, Ethylene Glycol (EG) was used as a capping agent in synthesis of HAp nanoparticles and Magnesium HAp nanocomposites. The synthesized n-HAp and Magnesium HAp nanocomposites were characterized using SEM, XRD, EDAX, FTIR and Antibacterial activity in order to analyze its structure, elemental composition and functional group.
XRD analysis shows the strongest 2θ peaks of n-HAp and Magnesium HAp nanocomposites at 32.1°, 25.9°, 49.7°and 10.2°, 32°, 18.9° respectively.
