United States Patent Application

View the Complete Application at the US Patent & Trademark Office
The present invention provides methods for the preparation of ceramic materials. Using the methods of the present invention, a porous ceramic material is impregnated with a metal-organic polymer and then treated with heat to decompose the polymer. Advantageously, the heat treatment may be performed at low temperature. The methods of the invention can be used to increase the density of a porous ceramic material or to change its composition. The methods are particularly useful for the formation of ceramic products in the form of films, coatings and layers in multilayer ceramic systems.
