Keramische Formkoerper mit sprunghaftem Strukturgradienten und Verfahren zu ihrer Herstellung

DE 10313847 A UPAB: 20041027 NOVELTY - A shaped ceramic body with an irregular structure gradient comprises at least two layers partially or completely one on the other of the same or different thickness. The transition between the layers comprises at least one irregularly changing structural characteristic. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a process for preparation of the shaped body which involves preparation of a suspension of the ceramic material, separation of the suspended ceramic powder, production of two or three layers, drying and sintering to give the required shaped body. USE - Useful for filters, burner elements, catalyst supports, and heat insulation plates. ADVANTAGE - The novel shaped ceramic body combines different workpiece properties in a single workpiece
