    Abstract: Formation of a refractory repair mass, in particular on an alumina-containing surface which is to be exposed to heavy duties, employs a powder mixture comprising alumina and, by weight, at least 5 % of a metallic combustilbe which is at least 30 % aluminium, and 3 to 10 % of an absorbency-reducing agent. A ceramic welding technique is used, in which the powder mixture is projected in gaseous oxygen against the surface to be repaired such that reaction between the combustible particles and oxygen occurs against the surface, thereby releasing the heat of reaction against the surface to form the repair mass.

    Abstract: A process is provided producing a crystalline siliceous refractory mass by projecting solid refractory particles, solid silicon particles and gaseous oxygen against a surface in such a way that reaction between the silicon particles and gaseous oxygen occurs against the surface, thereby releasing the heat of reaction against the surface so that a coherent refractory mass comprising cristobalite is formed, wherein the solid refractory particles comprise silica in the form of vitreous silica and in that the surface against which they are projected is at a temperature of a least 1000 DEG C. The process can be used for in situ repair of high temperature furnaces such as glassmaking furnaces or for the manufacture of high quality refractory bricks.

    Abstract: A carbon containing material for use in particular as an anode of electrolytic cells for the production of aluminium by the electrolysis of alumina in a cryolite-based electrolyte, consists substantially of a mixture of one or more particulate carbonaceous material(s) with a binder based on compounds of aluminium with carbon, oxygen and/or nitrogen, such as aluminium carbide or aluminium oxycarbide, or such compounds mixed with aluminium. This binder is obtained by mixing the particulate carbonaceous material(s) with particulate aluminium and with at least one compound of aluminium, lithium, cerium, calcium and sodium in a liquid carrier, and heat treating to form the binder. The liquid carrier may comprise a binding agent selected from methyl cellulose, polyvinyl alcohol and colloidal suspensions, in particular colloidal alumina.
