AB  - Pure phase orthorhombic pseudobrookite (Fe2TiO5) was synthesized using a modified sol-gel method. Bulk samples were obtained by uniaxial pressing of the obtained powder into compacts sintered at 900 °C for 2 h. A noticeable NTC thermistor effect was noted with a B20/55 value of 5747 K and high resistivity of 45 MΩcm at 25 °C. A non-linear current-voltage characteristic was observed in the voltage range (0.2–1100 V) at room temperature (25 °C). Non-saturated (lossy) P-E loops were obtained at both measured frequencies (100 Hz and 1 kHz) more expressed for the higher measured frequency, with the maximal polarization of 0.291 C/cm2 and remanent polarization of 0.123 °C/cm2 for 20 kV/cm2 and 1 kHz. Complex impedance measured in the temperature range 20–330 °C enabled analysis of the contribution of grain boundary and grains to the conduction mechanism. Bulk conductivity data determined in this temperature range was analyzed using Jonscher’s universal dielectric response model and showed that the conduction process followed the nearest neighbor hopping conduction mechanism.
