| Abstract: | For potential use as an electrode in SOFCs, the effects of lithium and magnesium doping for phase development and conductivity of LaTiO3 have been investigated. Using a 1000°C sintering temperature, dense ceramics are created via the traditional solid oxide reaction method. Phase study shows the presence of perovskite phase with monoclinic crystal assembly. Structural characteristics of doped and undoped perovskites were calculated using the VESTA tool. Through the computed XRD spectral analysis, unit cell dimensions are established. To quantify sub-atomic characteristics and examine lattice components, CrystalMaker software also calculates electron density and lattice range. CrystalMaker program is useful for simulating porosity distributions and analysing impure inclusions in crystallisation.The electrical conductivity of the perovskites was analysed using impedance spectrometry and Li-doped structures display a significant increase in conductivity in the phase borderline of disordered perovskite.
