A dielectric measurements study of the phase transitions in (Ba_0.6Sr_4.4)(Ti_1-xNi_x)O₃ transitions in ceramics with x ranging from 0.0 to 3.0 is reported. Both temperature transitions of respectively cubic-tetragonal and tetragonal-orthorhombic phase transitions are shitted to lower temperature with increasing Ni content. A change from normal to diffused phase transition is also observed in Ni-doped samples.
