Abstract

In ceramic welding processes, oxidising gas and a mixture of refractory and fuel powders are projected against a surface and the fuel is burnt to generate sufficient heat that the refractory powder becomes at least partially melted or softened and a cohesive refractory mass is progressively built up against that surface. In order to reduce any tendency for the weld mass to include a low-grade refractory phase and thus promote the refractoriness of that weld mass, the fuel powder is present in a proportion of not more than 15% by weight of the total mixture and comprises at least two metals selected from aluminium, magnesium, chromium and zirconium, at least the major part by weight of the refractory powder consists of one or more of magnesia, aluminia and chromic oxide, and the molar proportions of silica and calcium oxide present in the refractory powder (if any) satisfy the following expression: {SiO2} % </= 0.2 + {CaO} %. The elements of the fuel may be present in the form of an alloy.
