<p>A supporting matrix for catalytically active compounds, for use, for example, in catalysts for the catalytic cracking of nitrogen oxides, is constructed of a metal core (1), an intermediate layer (3) of vitreous enamel bonded onto this core, and a porous ceramic cover coating (5) applied to the vitreous enamel intermediate layer. The supporting matrix is made by dipping the metal core into a vitreous enamel slip followed by firing at 800 DEG to 900 DEG C. The enameled metal core is then fired in a second firing to form the ceramic cover coating which represents the actual support for the catalytically active compounds.</p> |
