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.

Cementitious yttria products [PDF]
An investigation has been made of the physical properties and formation conditions of cements formed in the yttria/salt/water system. Cementitious binders were of the nominal Y/sub 2/(OH)/sub 5/X.H/sub 2/O type (where X represents the Cl/sup -/ or NO/sub 3//sup -/).

Performance degradation and recovery of YSZ membrane under sulphuric acid thermal decomposition [PDF]
The effect of sulphur dioxide (SO2) present in the cathode feed stream on the performance of a 8 mole% yttria-stabilized zirconia/platinum (8YSZ/Pt) cell was studied. SO2 concentration of 30% in oxygen (5ml/min) and helium (30ml/min) was exposed to

Revealing the Giant Electromechanical Effects in Yttria-Stabilized Zirconia Single Crystal. [PDF]
Giant electromechanical responses are uncovered in yttria‐stabilized zirconia single crystal (SC‐YSZ), exhibiting pronounced orientation dependence. The giant electrostriction and piezoelectricity are directly correlated with the long‐range transport kinetics of oxygen vacancies.

Phase relations in the yttria–neodymia system at 1500 °C [PDF]
The phase equilibria in the binary system Nd2O3−Y2O3 at 1500 °C were studied in the overall concentration range by means of X-ray analysis and petrography.

Thick films of YSZ electrolytes by dip-coating process [PDF]
Yttria stabilized zirconia (YSZ, 8% Y2O3) thick films were coated on porous Ni-YSZ substrates using the dip-coating process and a suspension with a new formulation. The suspension was obtained by addition of a polymeric matrix in a stable suspension of a

Effects of PVA Polymer Type and Calcination Temperature on Synthesis of Nanocrystalline Yttria Powder by Polymer Solution Route [PDF]
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
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 ...
