Abstract

To permit using a single firing step, sintered aluminum nitride ceramic bodies provided with firmly adhering electrically conductive films or resistive layers can be produced by sintering of the green ceramic bodies and the films or layers in common, if these films or layers additionally contain a mixture of aluminum nitride and rare earth metal oxide.
