Eu-151-Mossbauer spectroscopic study on ceramics beloging to ZrO2-Eu2O3-Y2O3 system
Abstract
In the last years the ternary stabilized zirconia ceramics have attracted a considerable attention as a source of materials for structural ceramics. In present paper, the simultaneous influence of Eu3+ and Y3+ cations on zirconia powders (obtained by co-precipitation of aqueous salts solutions) on stabilization process in conjunction with the structural characteristics was investigated. A conventional sintering method (in electric furnace) at 1350 degrees C temperature range was applied. SEM+EDAX and XPS (X-ray Photoelectron Spectroscopic) analysis were performed. The Eu3+ Mossbauer parameters: isomer shift and quadrupole splitting have been obtained for 21.6 keV radiation of Eu-151 are in good agreement with the XPS and XRD-obtained crystallographic data of the studied compositions.
