Determination of the Cerium Oxidation State in Cerium Vanadate
Journal of the American Ceramic Society, 1995Use of low‐quality fuels in gas turbines can lead to vana‐dium hot corrosion of stabilized‐zirconia turbine blade coatings. The stabilizing oxide reacts with V 2 O 5 in the melt, forming a vanadate, thus removing the stabilizer from the zirconia.

Reduction and Sulfidation Kinetics of Cerium Oxide and Cu-Modified Cerium Oxide
Industrial & Engineering Chemistry Research, 2002The reducibility and H2S absorption capacity of cerium oxide and Cu-containing cerium oxide were examined in this work in the temperature range 623−923 K. The sorbents, prepared in bulk oxide form by the urea coprecipitation/gelation method, were composed of a cerium oxide backbone with a small amount of copper (5−40 atom %).

Variation in Density of Cerium Oxide
Nature, 1947The existence of polymeric varieties of cerium oxide was proposed so long ago as 18971, this contention being based, inter alia, upon the fact that the colour of the oxide is dependent, not only on its purity, but also upon the nature of the salt from which it is prepared by ignition.

Zeitschrift für anorganische und allgemeine Chemie, 1981
AbstractPhase equilibria in the (Ce, Te) O system, originating from interaction between Ce(NO3)3 · 6 H2O and H6TeO6 followed by calcination up to 700°C, have been studied by methods of physico‐chemical analysis (DTA, TGA, x‐ray diffraction, XPS). Evidence is given for the formation of non‐stoichiometric fluorite‐type mixed‐crystals (Ce, Te)O2 in the ...

Enhancement of Si oxidation by cerium overlayers and formation of cerium silicate
Physical Review B, 1986The oxidation of Si(100) surfaces covered with 3 A Ce was studied by high-resolution photoemission spectroscopy. The oxygen uptake was found to be enhanced by orders of magnitude by the presence of Ce. Because of chemical reaction between Ce and Si, a mixed oxide with a Ce:Si:O composition ratio of 1:1:3 is formed.

Adsorption of nitric oxide on cerium oxide
Journal of Colloid and Interface Science, 1982Abstract Adsorption of NO on evacuated CeO2 has been investigated by gravimetric, IR, and ESR measurements. On reduced sites, NO was decomposed into N2 or N2O accompanied by incorporation of oxygen into the surface. The oxygen adsorbed on the surface was identified by infrared study.
