Abstract

The present invention relates to a method of fabricating porous ceramic structures using the replication method and ceramics based on calcium phosphates (hydroxyapatite, tricalcium phosphate) alumina or zirconia as raw materials. The process is based on the selection of a polymeric substrate (polyurethane foam or another of the same type), to be replicated. The substrate is impregnated in a ceramic suspension (consisting of ceramic particles dispersed in a dispersant solution) and dried. The dried sponge is then taken to an initial sinterization in order to eliminate the polymeric substrate and then to a final sinterization, at high temperatures, for the densification of the ceramic network and con¬ sequently obtain mechanical resistance of the final structure. The proposed method allows the fabrication of porous three-dimensional structures with universal geometries, or specific geometries for a certain application, since this is a flexible method based on the identical replica of the polymeric substrate. The method also allows the fab¬ rication of structures with adequate raw materials for the intended application, by changing the ceramic powder composition. In this manner, the present invention can be used in ceramic composite industry, applying the proposed method in prostheses, orthodontia, bone implants, water filters, ion exchanges, catalyser supports, humidity sensors, etc.
