This study aims to investigate the electrical polarization of Ba1-xSrxTiO3 (x = 0.0, 0.2, 0.6, and 0.8) perovskite materials. The materials were synthesized using mechano-synthesis. The structural behaviour was assessed using X-ray diffractometer (XRD), revealing that all samples have a tetragonal perovskite structure with a lattice parameter that decreases with an increase in Sr. The electrical polarization was investigated using an electrometer, showing decreasing spontaneous and saturation polarizations as more Sr is substituted into the Ba sites of (Ba,Sr)TiO3. The decreasing lattice parameters and spontaneous and saturation polarizations in these materials indicate that the crystal structure changes from tetragonal to cubic as more Sr is added.
