ABSTRACT:
Ceramic honeycombs used as catalyst supports for combustion engine exhaust pollution control are provided with insulating porous refractory thermal barrier coatings disposed on and bonded to at least a portion of the external skins of the honeycombs, reducing the outer barrier coating surface temperature to provide thermal protection for the resilient fiber support materials used to mount the supports in catalytic converter enclosures.
