A catalyst support coating slurry resistant to gel formation and adapted to form a tightly adherent thermally durable coating on a refractory ceramic or metallized ceramic substrate, consisting essentially of fumed alumina in the amount of from 5 to 70 weight percent of the solids and at least one of the active alumina forming materials, e.g., gamma system aluminas, consisting of the alumina hydrates boehmite and pseudoboehmite in the amount of 30 to 95 weight percent of the solids, said aluminas being suspended in sufficient deionized water to form a slurry having the desired application characteristics and constituting about 30-36% by weight of said slurry.
