Popis:	Basic results on the development of an electrically conductive, wear and corrosion resistant ceramic composite material are presented. From a closer examination of the composition dependence of the electrical conductivity in the binary system ZrB2-B4C we determined the percolation threshold at which an interconnected network of electrically conductive phase arises: for the system investigated, at a critical volume fraction of about 10 up to 25 Vol.-% ZrB2 the electrical conductivity increased rapidly and above 40 Vol.-% ZrB2 an electrical conductivity similar to metals was observed (σe = 105–107 S.m-1).
