A method of repairing an oxide-based refractory body is described. The method comprises projecting a powder mixture against the surface of said body at an elevated temperature in the presence of oxygen. The powder mixture comprises oxide particles and fuel particles which react in an exothermic manner with the oxygen to form a refractory oxide. The invention is characterised in that the fuel particles are selected from magnesium, aluminium, silicon and mixtures thereof and in that the powder mixture additionally contains up to 10% by weight of silicon carbide particles. The invention provides a method of repairing oxide- based refractory bodies which enables a refractory repair mass to be formed with acceptable porosity.
