Abstract
In order to develop non toxic magnetic beads, influence of Fe addition to the hydroxyapatite was investigated, and Fe doped hydroxyapatite was prepared by hydrothermal process at 423K. The crystal phase of obtained samples had a hydroxyapatite related structure, and α-Fe2O3phase generated as a second phase at the ratio of Fe more than 5mol% additions. The ratio of α-Fe2O3 phase increased depending on the ratio of Fe, and 40 and 73% of added Fe existed as α-Fe2O 3 phase at 5 and 10mol % addition, and the estimated doped amount of Fe is about 2.1 mol% for 5mol% addition and 2.7 mol% for 10mol% addition, respectively. All samples showed paramagnetic property, and magnetization of sample increased depending on the ratio of Fe. The maximum magnetization of 0.63 Am2/kg was obtained at the Fe ratio of 10 mol %.
