HEAT-RESISTANT METAL MONOLITH AND MANUFACTURING METHOD THEREFOR

摘要

A heat-resistance metallic monolith, which is manufactured by forming metal powders into a shape of a honeycomb structure and by sintering the shape, has 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 and 1450.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.
