Abstract

A new process, GPM, has been developed to produce low density ceramic articles in any ceramic composition. This new process can produce articles with densities as low as 5% of the theoretical density (95% void fraction). The modulus of rupture values for the GPM material are in general 3-4 times as strong as the same density and composition ceramic foam. Products made with this new process are finding wide applicability in the catalyst and catalyst support media, low mass kiln furniture, ceramic pre-forms for metal/polymer infiltration and insulation markets. The microstructure, pore size and interconnectivity, and the fluid absorption properties of the GPM material are discussed.
