Abstract
Hydrolyzed or partially hydrolyzed mixtures of silicate esters and metal oxide precursors, are pyrolyzed at relatively low temperature in the presence of ammonia to form ceramic coatings on substrates such as electronic devices. The metal oxide precursors are soluble compounds, for example alkoxides, of aluminum, titanium, or zirconium. The coatings produced are useful for the protection of electronic devices. One or more coatings containing amorphous silicon, silicon carbon, silicon nitrogen, or silicon carbon nitrogen can be applied over the nitrided ceramic SiO.sub.2 /metal oxide coating for still further protection of electronic devices.
