Abstract
The purpose of the invention is a coating precursor comprising a silicone resin, a mineral filler and an organic solvent capable of dissolving the said resin and putting the said mineral filler into suspension, the said silicone resin and the said mineral filler being capable of chemically reacting so as to produce a solid layer on a substrate after the organic solvent has evaporated and a cohesive refractory layer after a calcination operation. Another purpose of the invention is a method for coating a given surface of a substrate with at least one refractory layer containing silicon in which the substrate is coated with a coating precursor according to the invention so as to form a green layer and a heat treatment is carried out to calcine the said green layer and to form a cohesive refractory layer. The invention is a means of obtaining a protective coating capable of resisting oxidizing environments, liquid metal and solid or molten salt.
