ABSTRACT:
A method of repairing an oxide-based refractory body by projecting a powder mixture against a hot surface of the body and in the presence of oxygen to provide a refractory repair mass includes providing a powder mixture composed of particles of at least one refractory oxide; fuel particles which react in an exothermic manner with the oxygen to form a refractory oxide and which are particles composed of at least one element selected from the group consisting of magnesium, aluminum, silicon, and mixtures thereof; and particles of silicon carbide present in an amount which is effective to provide a reduced porosity of the refractory repair mass and which does not exceed 10% by weight based on the weight of the powder mixture; and projecting the powder mixture against a hot surface of the oxide-based refractory body and in the presence of oxygen. Preferably, the powder mixture contains at least 1%, most preferably from 1 to 5%, by weight of the particles of silicon carbide. Preferably, the particles of silicon carbide have a particle size of less than 200 .mu.m.
