ABSTRACT:
The present invention relates to a rapid, low-temperature method of forming a ceramic or ceramic-like coating on a substrate. It comprises coating the substrate with a solution comprising a solvent and one or more hydrolyzed or partially hydrolyzed preceramic silicon alkoxides and, optionally, a ceramic oxide precursor. The solvent is evaporated and a preceramic coating thereby deposited on the substrate. The coated substrate is heated to a temperature of between about 40.degree. to about 400.degree. C. in the presence of ozone to ceramify the ceramic or ceramic-like coating. Additional protective coatings may be applied onto the coating thus produced.
