ABSTRACT:
This invention relates to a method of forming a ceramic coating on a substrate. The method comprises coating the substrate with a solution comprising a solvent and a silica precursor followed by evaporating the solvent to form a preceramic coating. The preceramic coating is then exposed to an environment comprising ammonium hydroxide or an environment to which water vapor and ammonia vapor have been added to facilitate conversion of the silica precursor to the ceramic coating. The preceramic coating is then subjected to a temperature sufficient to facilitate conversion of said preceramic coating to a ceramic coating.
