Abstract:
1. A method for treating a chamber having refractory walls, comprising: a spraying into said chamber, in the presence of oxygen, of a treatment composition comprising at least one organosilicon compound forming a majority portion by weight of said composition and at least one hydrocarbon capable, in the presence of oxygen, of giving rise, at a first temperature, to an exothermic reaction, and a rise in temperature of said sprayed treatment composition to at least said first temperature, characterized in that the spraying in the presence of oxygen takes place in the closed chamber where the treatment composition, in a predominantly liquid state, is atomized in the form of suspended particles, and in that the method further comprises during said exothermic reaction, a decomposition of said at least one organosilicon compound with formation of a colloidal silica aerosol in the closed chamber and the establishment of an overpressure therein, and a spreading of a colloidal silica layer on the refractory walls of said chamber with, following said overpressure, penetration of the colloidal silica into the microcracks of the refractory walls.
