Direct Extrusion Production of Monolithic Ceramics with Different Cross Section

Article Preview

Abstract:

The present work describes the fabrication of monolithic ceramics of different geometries through direct extrusion of ceramic pastes. Using this technique, ceramic rods with triangular, hexagonal, honey-like and tubular cross sections have been produced. The shape of some of these monolithic materials allows piling them up for building big catalytic reactors. After extruding and sintering, all processed ceramics have appropriate characteristics such as homogeneous texture, and controlled density and porosity. These results suggest the feasibility of using the extruded ceramics for different catalysis and filtering applications. Some features of the monolithic ceramics and the fabrication process will be analyzed.
