Abstract
A gelled film can be deposited directly on a sensitive substrate to obtain a protective ceramic coating on the substrate. An alumina sol, for example, can be sprayed through a flowing stream of ammonia to create a uniformly thick film, which adheres to metals, plastics, or, in some cases, water soluble materials. This film can then be cured, usually at low firing temperatures, to complete the coating.
