This invention relates to an improved method of making a distributor rotor electrode wherein dielectric particles are dispersed in an electrically conductive metal matrix for suppressing radio frequency intereference. More particularly, the invention relates to a method of making such electrodes wherein a mixture comprised of silica and copper oxide is fused into a solid material which is then comminuted into powder particles 50 microns in size, or less, and having irregular shapes. The powder particles themselves are comprised of a microscopic interspersion of a silica based phase and a copper oxide based phase. These powder particles are thereafter combined with a powder of an electrically conductive metal to form a uniform second mixture comprising about 0.5 to 15 weight percent silica. The second mixture is then pressed in a compact for a rotor electrode body and sintered to form a wear resistant densified rotor electrode.
