Solubility of erbium, praseodimiun and vananium in ZrO_2, ZrO_2-CeO_2 AND ZrO_2-Y2O_3

摘要

The equilibrium phase diagrams ZrO_2, ZrO_2-CeO_2 and ZrO_2-Y_2O_3 with erbium, preseodimium and vanadium oxydes have been investigated in the zone of tetragonal and cubic fluoritic solid solutions. The samples have been prepared from pyrolitic reactive powders, to attain equilibrium conditions at Low temperatures and short times. The samples, fired at 1400 deg.C, have been quenched and examined By XRD techniques.
