Abstract: The present invention provides a process for preparing a rare earth borate by reacting together at least one rare earth salt, boric acid and a base. The process is characterized in that the reaction is carried out using an excess of acid with respect to the stoichiometry and under conditions such that the pH of the reaction medium at the end of the reaction is in the range of 6 to 8. The precipitate formed is then recovered and calcined. The phase purity of the borate obtained is good and it can be used as a luminophore.

Abstract: The present invention relates to a compound of the LaMO3 type, M being aluminum, gallium or indium, in the form of a powder or in sintered form, its process of preparation and its use as an oxygen conductor. The compound in powder form is capable of achieving, by pressureless sintering, a density of at least 93% of the theoretical density and of giving a sintered compound substantially free of any electrically active secondary phase of the grain boundaries. The compound in powder form is obtained by the reaction of the salts of lanthanum and of the element M with a base, and then the separation and calcining of the precipitate obtained. It may also be obtained by mixing, in a liquid medium, salts of lanthanum, and of the element M and, optionally, of a base, and then spray-drying and calcining the precipitate obtained. The sintered compound may be used in any application requiring an oxygen-conducting material in oxide form, such as solid-oxide fuel cells.
