Microstructural and phase study of Y2O3 doped hydroxyapatite/Al2O3 biocomposİtes
Abstract
Hydroxyapatite is the mineral component of natural hard tissues and, as such, it has been studied extensively as a candidate biomaterial for its use in prosthetic applications. This study presents the fabrication and characterization of Y2O3 doped HA–Al2O3 composite materials. Hydroxyapatite (HA) powder was obtained from bovine bones (BHA) via calcination technique. Fine powders of HA/Al2O3 were admixed with 0.5 and 1 wt % Y2O3 powders. Powder-compacts were sintered at 1550°C for 4h. SEM, EDS and X-ray diffraction studies were conducted. The effect of increasing Y2O3 content on surface morphology, elemental distribution and phase evaluation was investigated in hydroxyapatite/Al2O3 biocomposite materials. © 2016, Inst Materials Physics.
