Effect of ion implantation doping on electrical properties of yttria-stabilized zirconia thin films [PDF]
, 1992 The change in conductivity of Fe and Ti implanted rf-sputtered layers of yttria-stabilized zirconia (YSZ) was studied as a function of the temperature (400–800°C) and oxygen partial pressure. In an oxidized state and in the temperature range of 400–600°C,

Effects of PVA Polymer Type and Calcination Temperature on Synthesis of Nanocrystalline Yttria Powder by Polymer Solution Route [PDF]
Archives of Metallurgy and Materials, 2018 Nano-sized yttria (Y2O3) powders were synthesized by a polymer solution route using polyvinyl alcohol (PVA) as an organic carrier. The PVA polymer affected the dispersion of yttrium ions in precursor sol.

Phase diagrams of zirconium dioxide systems with yttrium and scandium oxides
Конденсированные среды и межфазные границы, 2023 The literature data on the study of phase equilibria in systems zirconia with yttria and scandia are analysed. Possible schemes of low-temperature phase equilibria in ZrO2-Y2O3 and ZrO2-Sc2O3 systems are presented taking into account the third law of ...

Characterization of Fe implanted yttria-stabilized zirconia by cyclic voltammetry [PDF]
, 1992 The technique of cyclic voltammetry has been applied to study reduction and oxidation phenomena which are observed at low oxygen partial pressures during steady state current-overpotential measurements of the Au, O2(g)/Fe implanted yttria-stabilized ...

, 1978 A new, sinterable yttria (Y/sub 2/O/sub 3/) plaster was developed. The properties of this plaster depend on: (1) starting-power characteristics, (2) type and concentration of the acid used for the liquid phase, and (3) the liquid-to powder (L/P) ratios. Physical and chemical properties of the yttria plaster were investigated.

CVD of solid oxides in porous substrates for ceramic membrane modification [PDF]
, 1992 The deposition of yttria-doped zirconia has been experimented systematically in various types of porous ceramic substrates by a modified chemical vapor deposition (CVD) process operating in an opposing reactant geometry using water vapor and ...
