Abstract
The field of catalytic process requires ceramics supports with rigorous properties and a wide variety of shapes, this implies the generation of new materials with well geometric specific shapes. Extruded monolithics ceramics are actually being used extensively in catalytic reactors. The present work describes the fabrication of monolithic ceramics with diferent geometric shapes by direct extrusion of ceramic pastes. In this way monolithics ceramics with triangular, hexagonal, honey-rod and tubular cross section have been produced. The shape of some of these monolithic let its pilling for bulding some big catalytic reactors. After extrusion and sintering all ceramics present good physical properties such as: textural, density and porosity as well as good mechanical properties such as: hardness. These suggest their use in different kind of catalytic applications. Aspects of the monolthic ceramic fabrication process will be here analyzed.
