520			_a Hydroxyapatite (HAp) is a biomaterial that can be extracted from natural wastes. HAp has been widely used in biomedical applications owing to its excellent bioactivity, high biocompatibility, and excellent osteoconduction characteristics. However, most of the techniques and approached used to produce natural HAp incorporates chemical, that can sabotage the overall composition and properties of the HAp. This experiment summarizes the effects of alternative extraction method via heated ultrasonication from natural source, chicken bone. Extraction of HAp was achieved through boiling and heated ultrasonication. Dried and crushed bones were fired at 500℃, 700℃, and 900℃ for 2 hours with 10℃/min heating. SEM revealed that the HAp produced has a globular shape, and decreased particle size as temperature was increased. Ca and P are the most abundant elements found in the samples, and the calcination applied removed the carbon compounds of the HAp. Ca/P molar ratio of the produced HAp has higher stoichiometric ratio of 1.85 than 1.67 of pure HAp. Additionally, the microstructure of HAp produced using a non chemical procedure has comparable morphological shape size with the chemically produced HAp.
