Patent

CA 2417424

A fully inorganic boron nitride paste, containing 80 to 94% of a boron nitride paint and 6 to 20% of ceramic fibers, is provided to allow the process of manufacturing boron nitride "shell" coating of 0.0313 to 0.25 inch onto ceramic substrates chosen from a wide range of densities. De-clumping of the ceramic fibers such that fiber lengths are greater than 100 micrometers and clumps are less than 3/32 inch improves boron nitride "shell" layer uniformity. Boron nitride content of greater than 36 wt.% (or about 50 vol.%) in the boron nitride "shell" provides ceramic structures with a matrix of boron nitride that provides long-term nonwetting behavior for molten nonferrous metals.

Une pâte de nitrure de bore entièrement minérale, contenant 80 à 94 % d'une peinture au nitrure de bore et 6 à 20 % de fibres en céramique, est préparée en vue de permettre le processus de fabrication du revêtement <= coquille >= en nitrure de bore de 0,0313 à 0,25 pouce sur des substrats en céramique choisis parmi une grande variété de densités. La désagglomération des fibres en céramique telle que les longueurs de fibres sont supérieures à 100 micromètres et les agglomérations inférieures à 3/32 pouce améliore l'uniformité de couche de la <= coquille >= en nitrure de bore. Le contenu en nitrure de bore de plus de 36 % en poids (ou environ 50 % en volume) dans la <= coquille >= en nitrure de bore qui permet defournir des structures en céramique avec une matrice de nitrure de bore présentant un comportement non mouillant à long terme pour des métaux fondus non ferreux.
