Abstract
Ceramic filters processed by the replica method have been the subject of increasing research during the late years. In this research, ceramic filters of both 10 and 20 ppi of the systems Al2O3-LZSA and Al2O3-SiC, obtained by the replica method, have been mechanically evaluated using the compression test. The results of mechanical strength have been compared to Gibson and Ashby model. This paper proposes an adaptation of this model to explain the results.
