Answer 2

Present methods of forming ceramic articles, such as blowing, fusion-casting, slip-casting, pressing, drain-casting, drawing, and foaming, have been used for the production of a large variety of shapes. However, there has never been a completely successful means of forming a ceramic article with a large surface to weight ratio wherein the air spaces within could be of a predetermined size and shape and, optionally, continuous from one surface of the article to the opposite side. Articles of such congurations have extensive use as regenerators, recuperators, radiators, catalyst carriers, filters, insulation and the like, and have heretofore been made of ductile materials such as metals and alloys. While some ductile materials have properties which make them suitable for such purposes, it has been well-known that the wide variety of properties of ceramics, such as refractoriness, corrosion resistance, and low expansion, coupled with their relative low cost, 'would make them much more desirable for many applications. However, until now, the method of fabrication of such complex shapes from ceramic materials has been unknown.
