METHOD FOR CONVERTING SILICA PRECURSOR INTO SILICA AT LOW TEMPERATURE

摘要

This invention relates to a low temperature method of converting silica precursor coatings to ceramic silica coatings. The method comprises applying a silica precursor coating to a substrate, exposing the coating to an environment comprising ammonium hydroxide and/or wet ammonia vapors and subjecting the coating to a temperature sufficient to yield the ceramic coating. The methods of the invention are particularly applicable to applying coatings on electronic devices.
