PLATINUM AND RHODIUM CATALYSIS OF LOW TEMPERATURE FORMATION MULTILAYER CERAMICS

摘要

This invention relates to material produced by diluting in a solvent a platinum or rhodium catalyzed preceramic mixture of a hydrogen silsesquioxane resin. The preceramic mixture solvent solution is applied to a substrate and ceramified by heating. One or more ceramic coatings containing silicon carbon, silicon nitrogen, or silicon carbon nitrogen can be applied over the ceramified SiO2 coating. A CVD or PECVD top coating can be applied for further protection. The invention is particularly useful for coating electronic devices.
