Abstract:
A process for reconditioning a silica-based refractory article already subjected to high temperature and corrosive conditions in a furnace, to improve the corrosion resistance of the silica-based refractory article, comprising:(A) providing a silica-based refractory article already subjected to high temperature and corrosive conditions in a furnace; (B) impregnating the silica-based refractory article with a precursor which is an organometallic compound capable of being converted into a protective material; and (C) providing energy to the silica-based refractory article impregnated with said precursor and converting said precursor to said protective material thereby producing a silica-based refractory article impregnated with said protective material having improved corrosion resistance.
