ABSTRACT:
A composite filter element for filtering hot gasses is made up of a porous ceramic core to which a porous ceramic, thin outer layer is integrally bonded. The outer layer has a mean pore size which is at least several times smaller than the mean pore size of the substrate and the substrate is at least several times thicker than is the outer layer. The outer layer and the substrate are preferably formed of the same material or of two different materials having essentially the same coefficient of thermal expansion.
