Abstract In this paper there is described the technology of obtaining and results of investigations of microstructure, XRD, SEM, main dielectric properties, electrical conductivity measurements and P-E hysteresis loops of Ba0.6Pb0.4TiO3/graphene oxide composite (abbr. BPT/GO). In the final step of technology, the samples have been sintered using the Spark Plasma Sintering (SPS) method. Diffraction patterns of BPT/GO composite exhibit lines which can be related with perovskite structure, as well as reveal additional lines that can be derived from the initial component oxides. Investigations of electrical conductivity suggest that the PTCR effect occurs at temperatures up to about 120°C. Dielectric hysteresis loops below 90°C are wide and typical for materials with rather high electrical conductivity. The hysteresis loop obtained at 120°C is more typical for ferroelectrics. The obtained material is interesting, however it is probably possible to find better conditions of obtaining it and/or a better composition.
