%0 Journal Article %T Effect of Sintering Atmosphere on Phase Evolution of Hydroxyapatite Nanocomposite Powders %A Ebadzadeh T. %A Salahi E. %A Ebrahimi M. %J Proceedings of the International Conference Nanomaterials : Applications and Properties %D 2012 %I Sumy State University %X In the present work, pure hydroxyapatite, hydroxyapatite -20 wt% alumina and hydroxyapatite -20 wt% titanium mixtures were pressed and sintered in air, moist, and reduction atmospheres at 1200oC for 2 h. XRD investigations of sintered samples showed that, pure hydroxyapatite is stable in all three atmospheres. But, moist and reduction atmospheres were preferred to suppress the hydroxyapatite decomposition in hydroxyapatite -alumina and hydroxyapatite ¨Ctitanium nanocomposites, respectively. %K Nanomaterials %K Nanobiotechnology %K Pharmaceutics %K Biochemical engineering %K Diagnostics and treatment methods %U http://nap.sumdu.edu.ua/index.php/nap/nap2012/paper/view/395
