EVIDENCE OF ELECTRICAL CONDUCTIVITY IN LI(4-2X)NIXTI2O6 DOUBLE PEROVSKITE

The polycrystalline nature of Li Ni Ti O (where X = 0, 0.25, 0.50, 0.75) (LNT) were synthesized by sol-gel method and (4-2x) x 2 6 microwave processing method. The powder X-ray diffraction technique confirms the monoclinic crystal structure and C2/c space group. The high resolution scanning electron microscope studies revealed particle size 30 [1]. The temperature scan of conductivity demonstrated the existence of thermally generated charge carriers. The conduction mechanism in LNT compositions is discussed and found to be band type conduction
