(Pb0.87Ba0.08Sr0.02La0.02)(Zr0.65Sn0.27Ti0.08)O-3 ceramics with uniform and dense microstructure were papered by the traditional solid state reaction process, and the antiferroelectric (AFE) nature was confirmed by 'double hysteresis loops and dielectric behavior. The temperature had a great impact on the field dependence of the dielectric behavior that exhibited three kinds of shapes from 20 degrees C to 90 degrees C. Unique dielectric behavior indicated that the AFE ceramics obtained had a promising for tunable microwave devices.
