A silicon carbide (SiC) powder compact was prepared with submicrometer β‐SiC, yttrium nitrate as a sintering additive, and polysiloxane‐phenol resin as precursors for nanosized SiC. By hot‐pressing, fully dense SiC ceramics with good electrical conductivity, as high as 3 × 10 4 (Ω·m) −1 at room temperature, were obtained. The ceramics could be machined to complex shapes by electrodischarge machining.
