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.

Partial oxidation of ethanol on Ru/Y2O3 and Pd/Y2O3 catalysts for hydrogen production

Catalysis Today, 2007
Abstract The partial oxidation of ethanol was investigated over Ru and Pd catalysts supported onto yttria over a wide range of temperatures (473–1073 K). The product distributions obtained over these catalytic systems were correlated with diffuse reflectance infrared spectroscopy analyses (DRIFTS). Results showed that reaction route depended strongly

The influence of activation of Y2O3 polycrystalline matrices by Bi3+ ions on the luminescence of Y2O3:Eu3+

Inorganic Materials, 2009
The influence of activation of the Y2O3 matrix of the Y2O3:Eu3+ phosphor by Bi3+ ions on the luminescence of Eu3+ and Bi3+ ions in it and on conditions of the excitation energy transfer to luminescence centers is studied. It is shown that the presence of Bi3+ ions leads to the appearance of recombination luminescence with participation of bismuth ions ...
