Abstract
PURPOSE: To obtain the titled support excellent in durable strength and buffer effect to vibration, by alternately stacking an unformaed layer and a foamred layer comprising a ceramic material.
CONSTITUTION: A foamed ceramic support 4 is provided to the gap between a catalyst carrier 2 and a case 3 and prepared by a method wherein a ceramic sheet obtained by coating a foamable ceramic film on a strip like ceramic paper is wound around the outer periphery of the carrier 2 in a layered form to be arranged in the case 3 and the foamable ceramic film is foamed in said case 3 to form alternately laminated foamed layers 8 and unfoamed layers 6". By this laminate structure, structual strength of the more rigid unfoamed layer 6" inserted and provided between the foamed layers 8 is increased. In addition, because the unfoamed layer 6" and the foamed layer 8 are made of ceramic materials having same quality, both layers 6", 8 are adhered strongly and closely as well as, because coefficients of thermal expansion of both layers 6", 8 are almost equal, breakage due to difference of thermal expansion is inhibited.
