ABSTRACT:
A heat-resistant metallic monolith manufactured by forming metal powders into a honeycomb structure and by sintering the structure, a heat-resistant metal oxide coated on the surface of the cell walls and that of the pores thereof. Such a heat-resistant metallic monolith is manufactured by mixing metal powders, an organic binder and water to prepare a mixture, by forming the mixture into a shape of a desired honeycomb configuration, by sintering the shape in a non-oxidizing atmosphere at a temperature between 1000.degree. and 145.degree. C. and then by coating a heat-resistant metal oxide on a surface of the cell walls and that of the pores of the obtained sintered body.
