A conductive sialon sintered body can be obtained from silicon nitride, from 6 to 25% by weight of sintering aid, based on the silicon nitride, and from more than 30% by volume to less than 70% by volume of titanium nitride, based on the total amount of silicon nitride and sintering aid. The sintering aids essentially consist of from 3 to 10% by weight of Y2O3, from 2 to 7% by weight of AlN or AlN of the polytype and from 1 to 8% by weight of Al2O3, based on Si3N4. This conductive sialon sintered body is obtained by sintering the corresponding green shaped body in a nitrogen atmosphere at from 1600 to 1900 DEG C at 300 bar or less, preferably under atmospheric pressure.
