Zusammenfassung:	A process for producing a catalyst having a heating element that is formed from an electrically conductive metal alloy. In the production process, the catalyst undergoes at least a first heat treatment, during which the catalyst is at least partly heated in defined fashion and cooled in a defined fashion. The steps include heating at least a subregion of the catalyst to a predeterminable temperature of at least 550 degrees celsius, holding the temperature at a constant temperature level for at least two minutes, and cooling the at least one subregion of the catalyst at a temperature transient of at least 500 Kelvin per minute.
