ABSTRACT:
A method of manufacturing an open-celled ceramic article having high wall strength, the article comprising a plurality of spaced walls of bondable material defining a plurality of elongate passage therethrough which are filled with a disintegratable filler material during the forming process, the surfaces of the filler material being coated with a partially disintegratable material comprising particles of boron nitride or other substance which is chemically inert with respect to the filler material and with respect to the walls. The coated filler material has sufficient form and strength to initially maintain the walls in their predetermined precisely spaced relation. After the walls are bonded into an integral unit, the filler material and the protective coating are independently removed from the article to re-establish the passages between the walls.
