Abstract

L'invention concerne en général un procédé servant à contrôler la dimension des pores, la répartition de cette dimension et la porosité de céramiques à base d'oxyde d'aluminium et consistant à sélectionner des substituants de carboxylate-alumoxanes et de nanoparticules d'oxyde d'aluminium. Ce procédé permet d'obtenir des pores intragranulaires de l'ordre du nanomètre à créer dans des corps de céramique d'alumine et d'oxyde d'aluminium. On effectue le contrôle de la dimension des pores et de la répartition de cette dimension par l'intermédiaire de différents substituants chimiques des carboxylate-alumoxanes et des nanoparticules d'oxyde d'aluminium. La dimension et la répartition des pores à l'intérieur de la céramique d'oxyde d'aluminium dépend de l'identité des substituants de carboxylate. En particulier, la formation d'une porosité intragranulaire par rapport à une porosité intergranulaire dépend de l'identité des substituants de carboxylate. L'invention concerne également des procédés servant à fabriquer des revêtements de céramique sur des fibres de céramique et de carbone pour des mises en application composites et des membranes de céramique présentant des dimensions de pores de l'ordre du nanomètre. On contrôle la dimension des pores, la répartition de la dimension des spores, la porosité et, de ce fait, la résistance, la perméabilité et l'adhérence de surface du revêtement de céramique au moyen du choix du substituant de carboxylate-alumoxane. La thermolyse de couches centrifugées autonomes de ces carboxylate-alumoxanes permet d'obtenir des disques d'alumine dont la dimension de pores, la répartition de cette dimension et la porosité ont été contrôlées. Dans un autre mode de réalisation, on trempe un substrat poreux dans une solution de carboxylate-alumoxane ou on le revêt de cette solution, puis on le soumet à une thermolyse afin d'obtenir une membrane composite.
