Preparation and conductivity of Yb2O3–Y2O3 and Gd2O3–Y2O3 co-doped zirconia ceramics

Solid State Ionics, 2008
Abstract A suspension stabilizer-coating technique was employed to prepare x mol% Yb2O3 or Gd2O3 (x = 1.0, 2.0, 3.0 and 4.0) co-stabilized 1.0 or 2.0 mol% Y2O3 doped ZrO2 nanopowders (xYb1Y, xYb2Y, xGd1Y). Fully dense Yb2O3/Gd2O3 and Y2O3 co-doped ZrO2 ceramics were obtained by means of pressureless sintering in air at 1450 °C.

Nano/Micro-Laminated (ZrO2–Y2O3)/(Al2O3–Y2O3) Composite Coatings and Their Oxidation Resistance

Oxidation of Metals, 2007
Nano/micro-laminated (ZrO2–Y2O3)/(A12O3–Y2O3) composite coatings were deposited onto an Fe–25Cr–7Ni–N alloy substrate by using alternate electrochemical and sintering processes. The thickness of each layer was in the range of 80–500 nm. Experimental results indicated that the multi-laminated coatings were more effective in providing oxidation ...

Синтез нанопорошков ZrO2-Y2O3

2020
Formation of Zr02-5 wt.% Y20 3 nanostructured powders in glycine-nitrate combustion synthesis was investigated and the effect of "glycine-to-N03" ratio and heating method on the reaction product composition and particle morphology studied. Ammonium nitrate additive was used to optimize the regime of the process.

Phase Relations along the Y2O3–CuWO4Join in the Y2O3–WO3–CuO System

Inorganic Materials, 2001
The phase relations in the Y2O3–WO3–CuO system were studied by x-ray diffraction and thermal analysis. The results were used to construct the 800°C section of the phase diagram. Based on the new and earlier data on the liquidus relations, the section through the Y2O3–WO3–CuO phase diagram along the Y2O3–CuWO4join was mapped out.
