A Study of Preparing Samples of Hydroxyapatite with Different Densities Using Charcoal Powder

Abstract

Abstract The powder of hydroxyapatite with the chemical formula Ca10 (PO4) 6 (OH) 2 was prepared locally from cow bones in the hexagonal crystal phase, and this was confirmed through the X-ray diffraction system. The proportions that formed the prepared hydroxyapatite were confirmed through the X-ray fluorescence system and found the ratio of calcium oxide to phosphorous oxide is 1.718. The hexagonal phase of the prepared hydroxyapatite was also stabilized ( fixed ) for the samples before and after the heat treatment. Some physical and mechanical properties were also conducted for the prepared samples. It was found that it is possible to prepare samples of different densities by adding different proportions of carbon (charcoal) percentage to the prepared hydroxyapatite.
