CERAMIC-CERAMIC COMPOUNDS, SUITABLE FOR ELECTRICAL APPLICATIONS

摘要

Process for producing ceramic materials made of an essentially dielectrical ceramic matrix, having at least one electroconductive area, and compounds produced by said process. An area of an oxide-based matrix, which will form said electroconductive area, is contacted with a carbon precursor; the matrix is submitted to thermal processing so that carbon is released by the precursor and said precursor is reacted with at least one of the matrix oxides, whereby, in said zone, one layer of the matrix material is transformed into a layer of electroconductive stable carbide.
