<p>Method of treating a chamber having refractory walls, in which: a treatment composition, comprising at least one organosilicon compound and at least one hydrocarbide, is sprayed into said chamber, in the presence of oxygen; and said sprayed treatment composition is heated, the spraying in the presence of oxygen taking place in the closed chamber in which the treatment composition, in a predominantly liquid state, is atomized in the form of suspended particles, the method further including said at least one organosilicon compound decomposing to form a colloidal silica aerosol in the closed chamber, an overpressure being established therein, and a colloidal silica layer being spread over the refractory walls with, as a result of said overpressure, the colloidal silica penetrating into the microcracks.</p> |
