Stabilization of beta -Bi sub(2)O sub(3) by hafnia

The addition of HfO sub(2) into Bi sub(2)O sub(3) causes stabilization at RT of the beta -phase. This material is characterized by XRD, TEM, EDAX and time-differential perturbed-angular-correlation spectroscopy (PAC). The beta and delta phases were detected and characterized. The oxygen vacancy occu...

Zusammenfassung:The addition of HfO sub(2) into Bi sub(2)O sub(3) causes stabilization at RT of the beta -phase. This material is characterized by XRD, TEM, EDAX and time-differential perturbed-angular-correlation spectroscopy (PAC). The beta and delta phases were detected and characterized. The oxygen vacancy occupation is compared with beta -Bi sub(2)O sub(3) stabilized by other oxides.
