Zusammenfassung:	A catalyst composition effective after exposure to temperatures greater than 1000 DEG C, incorporating at least three types of particles dispersed on a ceramic substrate: thermally stable alumina support particles stabilized with either lanthana and baria or a high molecular weight polyorganosiloxane having palladium dispersed thereon; catalytic metal oxide particles for promotion of combustion of carbon monoxide; and inert thermally stable washcoat stabilization particles.
