  • Process for forming a refractory repair mass
    Patent number: 5928717
    Abstract: A powder mixture for use in ceramic welding repair of a refractory material containing alumina includes refractory particles including alumina; at least 5% by weight of a metallic combustible which is at least 30% aluminum; and from 3 to 10% by weight of an additive which is at least one material selected from the group consisting of aluminum fluoride, barium sulfate, cerium oxide, and calcium fluoride. A process for repairing a refractory material which contains alumina includes providing the above powder mixture; and projecting the powder mixture against a surface of the refractory material in the presence of gaseous oxygen so that the combustible particles and the gaseous oxygen react and release the heat of reaction against the surface and form a coherent refractory mass.
