The present invention relates to a method of forming a refractory mass on a surface, in which a mixture of refractory particles and partially melted oxidizable particles is sprayed. BR/ The granulometric distribution factor of the 80% and 20% pasty fractions of the refractory particles and oxidizable particles is less than 0.8. The present invention also relates to a composition of a mixture of particles for the implementation of such a process.
