ABSTRACT:
Catalysts of reduced cost, for purifying exhaust gases, having smaller thermal expansion coefficients than conventional catalysts, good mechanical strength and large specific surface area are provided at low temperatures. The composition composed of at least re-hydrable alumina, an alkali or alkaline earth metal titanate and fused silica is thermally processed at comparatively low temperatures so as to provide ceramic catalyst carriers which have superior properties.
