Patent

CA 2331434

The invention relates to a process for production of a sintered oxide ceramic of composition Ce x M y D z O2 -a with dense structure without open porosity or with a predetermined porosity. The first doping element M is at least one element of the group consisting of the rare earths but M ~ Ce, alkali and earth alkali metals. The educts are used with a second doping element D of at least one metal of the group consisting of Cu, Co, Fe, Ni and Mn, in the submicron particle size or as a salt solution, and sintered at a temperature in the range of 750 - 1250°C into an oxide ceramic with extremely fine structure of a grain size of maximum around 0.5 µm.
