  • Publication number: 20150258533
    Abstract: The invention relates to a component for high-temperature applications, to a method for the production thereof and to a use thereof. In this respect, an electrical conductivity and a catalytic effect should be achievable with a simultaneous chemical and thermal resistance under different conditions and also at temperatures above 700° C. The component in accordance with the invention is formed from a body which is formed from Ce1-x-yLnxMeyO2. In this respect, Ln is a rare earth metal and Me is a transition metal, where x=0.01 to 0.25 and y=0.05 to 0.2. Particles having a mean particle size in the range from 5 nm to 500 nm, preferably in the range from 10 nm to 300 nm, and formed using transition metal, are present in a distributed arrangement on at least one surface.
