ABSTRACT:
A process for preparing a hollow, porous ceramic material is provided. In the first step of the process, a substrate which will burn out (vaporize) at a temperature of 1,100 degrees Fahrenheit (and which, preferably, is carbonaceous) is provided. This substrate is coated with a mixture of gluten, ceramic material, and water. The coated substrate is then dried to a moisture content of less than about 0.5 weight percent and, thereafter, heated to a temperature of from about 1,100 to about 3,200 degrees Fahrenheit to cause the substrate to burn out and the coating to sinter.
