Production of ceramic materials by pyrolyzing the reaction mixture containing an aluminum compound

Abstract From the Canadian patent

A process for the production of a refractory compound, e.g. a carbide or nitride, of a metallic or non-metallic element, by reacting a mixture of a compound of the metallic or non-metallic element having at least two groups reactive with hydroxyl groups and an organic compound having at least two hydroxyl groups to produce an oxygen-containing polymeric product and, pyrolysing the polymeric product, e.g. in an inert atmosphere to produce a carbide or in an atmosphere of reactive nitrogen compound to produce a nitride in, which the reaction mixture contains an aluminium compound containing at least one group reactive with hydroxyl groups. The presence of the aluminium compound in the …
