Als Werkstoff für die Draht-Armiemng 20 kommt bevorzugt ein Draht aus einer Lt gierung in Frage, welche Legierungsbestandteile aus Chrom, Aluminium und/oder Kobalt enthält. Die Hülle selbst kann aus einem hitzebeständigen Zement oder auch aus einer Kittmasse auf der Basis von Mineralfasern bestehen. The material for the wire armament 20 comes preferably a wire made of a Lt alloy in question, which alloy components made of chrome, aluminum and / or contains cobalt. The shell itself can be made from a heat-resistant cement or from consist of a cement mass based on mineral fibers.

Als Werkstoff für das Gehäuse kommt für alle Ausführungsformen bevorzugt ein Nickel-Chrom-leoierter Stahl mit austenitischem Gefüge, der bis zu 1150° C hitze- und zunderbeständig ist, in Frage.A nickel-chromium alloy is preferably used as the material for the housing for all embodiments Steel with an austenitic structure that is heat and scaling resistant up to 1150 ° C is in question.

Die Dichtungs- und Stützbänder bestehen vorteilhaft aus chemisch stabilen, unbrennbaren Mineralfasern, im wesentlichen aus Aluminiumoxyd und Siliziumoxyd.

Als Bindemittel ist ein an der Luft härtender oder unter Temperatureinwirkung aushärtbarer hiizebeständiger Werkstoff geeignet. Der Werkstoff muß beim Aufbringen der Hülle plastisch verformbar sein damit er sich dem Raum zwischen Katalysatorkörper und Hülle anpassen kann.The binder is an air-hardening or Heat-resistant hardenable under the influence of temperature Material suitable. The material must be plastically deformable when the shell is applied so that it can adapt to the space between the catalyst body and the shell.

Für den Katalysatorkörper selbst kommen unterschiedliche Werkstoffe in Frage, je nachdem, ob es sich um einen Oxydations- oder einen Reduktionskatalysaior handelt.For the catalyst body itself, different materials come into question, depending on whether there is an oxidation or a reduction catalyst acts.

Sein die feinen Durchströmungskanale enthaltendes Skelett besteht aus einem feuerfesten keramischen Werkstoff, beispielsweise aus Magnesium-Silikat Aluminiumoxyd, Zirkon od. dgl. Dieses Skelett dient als Träger für eine dünne Auflage aus dem Material mit der katalytischen Wirkung.Its skeleton containing the fine flow channels consists of a refractory ceramic Material, for example made of magnesium silicate aluminum oxide, zirconium or the like. This skeleton serves as a carrier for a thin layer of the material with the catalytic effect.
