Abstract
Porous green ceramic parts may be prepared by componding 90 to 60 weight percent of a particulate ceramic material with 10 to 40 weight percent, on a dry basis, of a latex of a polymer. The compound is frothed, shaped and set. The green part may then be sintered. The process avoids the expense of preparing solid ceramic compounds containing waxes or sawdust which burn out to create voids. The process is useful to prepare ceramic filters, catalysts, or light weight metal ceramic foams.
