Abstract

Procédé de fabrication de spinelle de magnésium à partir de sulfate de magnésium et d'une solution d'aluminate de sodium obtenu par le procédé Bayer par co-précipitation et recuit On fait réagir des quantités équimolaires de sulfate de magnésium et d'aluminate de sodium en présence d'acide sulfurique. Le précipité obtenu est séparé de la phase liquide, lavé et recuit à une température de 900 à 1 100 degrés C. On obtient ainsi un spinelle stoechiométrique. Le spinelle de magnésium obtenu trouve des applications dans l'industrie de la céramique, de l'électronique et des catalyseurs.Process for manufacturing magnesium spinel from magnesium sulfate and a sodium aluminate solution obtained by the Bayer process by co-precipitation and annealing Equimolar quantities of magnesium sulfate and sodium aluminate are reacted in the presence of sulfuric acid. The precipitate obtained is separated from the liquid phase, washed and annealed at a temperature of 900 to 1,100 degrees C. A stoichiometric spinel is thus obtained. The magnesium spinel obtained finds applications in the ceramics, electronics and catalyst industries.
