Effect of excess PbO on microstructure and mechanical properties of (Pb<inf>0.975</inf>Ba<inf>0.025</inf>)ZrO<inf>3</inf>ceramics

(Pb0.975Ba0.025)ZrO3(PBZ2.5) ceramics were fabricated from their oxide mixture via the solid state reaction method. Excess PbO (1, 3, 5 and 10 wt%) was added together with starting materials to compensate for PbO loss from evaporation during calcination and sintering. The phase structure was analyze...
