Abstract

A ceramic article is obtained by mixing silica and/or one or more metal oxides with one or more metals which includes a metal capable of undergoing autothermic firing with one or at least one of the oxides and bring a metal different from the metal of such oxide, compacting, shaping and heating the mixture under conditions conducive to autothermic firing, the proportions of the reactants being such that not all of the oxide is reduced and free silicon or metal, if liberated from the oxide, is uniformly distributed throughout the article. Up to 50% of a chemically unreactive combustible e.g. wood and/or anthracite may be included for additional porosity and when two mixtures having differing amounts of combustible are placed adjacent to each other and fired, an article having different zones of porosity is obtained. Oxides specified are those of aluminium, chromium, magnesium, titanium and thorium e.g. bauxite, chromite, chromia, grog, ilmenite, magnesia, mullite, sillimanite, thoria and titania, p whilst aluminium is the preferred metal. Silicon carbide may also be present, as may also ball clay, china clay and fireclay, the fireclay may even be used as the oxide component. The article may be further heated in an oxidizing atmosphere. The first Provisional Specification includes the oxides of tin and nickel.
