PURPOSE:To reduce the thermal deterioration of the titled catalyst, by supporting the catalyst fine powder, wherein a catalytic material is preliminarily supported by the surface of a high temp. sintered ceramic fine powder, by the surface of a catalyst carrier. CONSTITUTION:A catalyst material, wherein a silica cloth or honeycomb base material is coated with a carrier such as silica, alumina, cordierite, magnesia or titania, is supported by the surface of a ceramic body obtained by sintering a fine powder with a particle size of 0.1-1mum comprising alumina, zirconia or cordierite at a high temp. |
