    Li-doped BaTiO3 nanoparticles with Li+ mole fraction, x, such as 0 ≤ x ≤ 0.30 (BLxT) have been successfully synthesized bythe sol-gel method and their structure examined with X-ray diffraction (XRD) technique. The latter showed that thesematerials, heat treated at 1000 oC during 4hrs; crystallize in the pure tetragonal phase for the undoped sample (BT),whichtransforms into pseudo-cubic phase for x ≥ 0.05. These results were confirmed by Raman analysis. The thermal behavior ofthe permittivity and the conductivity was studied and in particular the thermal behavior of the latter revealed the PTCR effect.
