Pure and 5% Mg-doped BaZr_0.1Ti_0.9O₃ (BZT) ceramics have been prepared by the conventional solid-state route. Microstructure, dielectric properties, and ferroelectric behaviour of samples sintered at different temperatures were investigated. The results indicate that Mg⁺² ions facilitates the formation of the perovskite phase during the calcination process, lowering the sintering temperature of the ceramics. We show that Mg-doped ceramics sintered at 1250 ^oC display better dielectric and ferroelectric properties than pure BZT. The addition of 5% of magnesium leads to the decrease of the Curie temperature by ~ 75 ^oC.
