<p>A method for producing a corrosion-, heat- and oxidation-resistant material which comprises coating a substrate composed of at least one material selected from metals, carbonaceous substances and ceramics with a semi-inorganic compound, and heat-treating the coated substrate; said semi-inorganic compound being either (1) a modified organoborosiloxane compound obtained by reacting an organoborosiloxane compound with at least one organic compound selected from the group consisting of polyhydric aliphatic alcohols, aromatic alcohols, phenols and aromatic carboxylic acid at a temperature of from 250 DEG to 450 DEG in an atmosphere inert to the reaction, or (2) a modified organoborosiloxane compound obtained by adding at least one catalyst selected from the group consisting of Ni, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Co, other transition metals, actinoid metals, lanthanoid metals, alloys of these metals, persulfate salts, organic peroxides, and halides of Al, Fe, B, Ga and In to an organoborosiloxane compound, and heating the mixture in a non-oxidizing atmosphere at a temperture of 300 DEG to 550 DEG C.</p> |
