We successfully prepared pure CrNpowder by ammonolysis of anhydrous chromium (III) chloride, which was confirmed by X-ray diffraction analysis (XRD) and SEM-EDS. CrNceramics were then prepared by classical ceramic route (CCR) and by spark plasma sintering (SPS) at different sintering conditions. Transportproperties (Seebeck coefficient, electrical resistivity and thermal conductivity) were measured in the range 2–600 K and the magnetic behaviorwas examined by SQUID. Above the room temperature thermal conductivity was obtained by laser flash analysis (LFA). Thermal stability andthermodynamic characteristics were probed by simultaneous thermal analysis (STA). Transport properties are strongly affected by the fabricationprocess and the resulting figure of merit (ZT) is surprisingly high.
