摘要:
A process for producing an improved ceramic fiber molding by submersing the molding into a suspension containing colloidal silica and/or colloidal alumina and chromium oxide powder. The chromium oxide is deposited onto the ceramic fibers thereby increasing the molding's resistance to linear shrinkage and corrosion when subjected to high temperatures.
