Author(s): Faten Nouri, RiadhTernane, Malika Trabelsi-Ayadi

A new chlorapatiteBa10(VO4)6C 2has been synthesizedby the solid-state reaction and characterized byX-ray diffraction, infrared absorption and Raman scattering spectroscopies. Electrical properties of the material have been studied by the compleximpedancespectroscopy. Nyquist plots show negative temperature coefficient of resistance (NTCR)-type behavior. The total conductivity of the material is thermally activated with activation energy about 0.39 eV.
