ABSTRACT:
Silica-containing ceramic coatings are produced on substrates at low temperatures by applying a coating comprising a silica precursor on a substrate and heating the coated substrate under an environment comprising nitrous oxide at a temperature sufficient to convert the silica precursor to the silica-containing ceramic coating. This method is especially valuable for forming protective and dielectric coatings on electronic devices.
