The objective of this work was to evaluate the effect of processing parameters on the permeability and mechanical resistance of cellular ceramic filters. Analyses included processing and characterization of 8 ppi Al2O3-SiC filters produced from ceramic suspensions with different particle size distributions. The purpose was to optimize the particle packing in the solid struts and thus improve the mechanical properties of the filter without reducing its permeability. Characterization included evaluation of rheological properties of suspensions as well as measurements of porosity, permeability and mechanical resistance of the produced filters.
