ABSTRACT:
A process for producing a porous ceramic, ceramic composite or metal-ceramic composite structure by combustion synthesis wherein a foamed polymer shape is impregnated with a slurry of ceramic precursors and ignited to initiate combustion synthesis, thereby obtaining a ceramic, ceramic composite or metal-ceramic composite article having interconnected porosity. Ceramic composite filters having improved strength, toughness and thermal shock resistance are provided, with the ceramic composite being an oxide and a nonoxide.
