Abstract
Natural hydroxyapatite (HAP) is isolated from waste chicken bone by thermal calcinations at
different temperatures in the range of 200 ◦C to 1000 ◦C. The isolated HAP has been characterized using thermo gravimetric analysis (TG) and differential thermal analysis (DTA), Fourier
Transformed Infrared spectroscopy (FTIR), X-ray diffraction (XRD), field emission electron
microscope (FE-SEM), and energy dispersive X-ray (EDX). The XRD results showed that the
enhanced crystallinity of HAP phase by thermal calcination above 600 ◦C and the crystal size
has been found to increase with increasing temperature of thermal calcinations due to agglomeration. Value addition for the waste chicken bone is given by the isolation of useful bioceramics
(HAP) and the optimum temperature for the thermal calcination is found to be 600 ◦C. The
isolated HAP has been characterized as carbonated HAP of B type with the hexagonal structure.
