PROCESS FOR PRODUCING HARD FORMABLE MATERIAL HAVING CHANNEL FOR PASSING LIQUID THERETHROUGH, MATERIAL PRODUCED BY SAID PROCESS AND ITS USE

摘要

PURPOSE: To produce a hard, shapable material having channels for the passage of fluids. CONSTITUTION: A cluster of several particles is formed from particles with the aid of a binder, the cluster is brought into the form of a cohesive structure with the aid of a binder in a further working step, and the structure has a plurality of interconnected cavities. The porosity of the surface breaks down the surface clusters into fragments and embeds them in surface openings.
