Synthesis and Characterization of Hydroxyapatite from Biowaste Eggshells for Medical Application

Hydroxyapatite (HAp) powder was successfully preparation by using biowaste eggshells. These shell were transform to calcium hydroxide (Ca(OH)2) reacted with ortho-phosphoric acid (H3PO4) as the precursors for sol-gel method. The effect of ageing temperature on the physical properties was studied at room temperature and 100 ºC. The synthesized HAp was characterized by Fourier Transfrom Infrared spectrometer (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM) and Energy Dispersive X-Ray spectroscopy (EDS). The Results showed that obtained HAps were high purity and cylinder shape. Crystalline structure of HAp was increased at 100 ºC 24 h and had mole ratio of Ca : P = 1.97.
