Thermal Treatments Effects on Microwave Dielectric Properties of Ba(Zn1/3Ta2/3)O3 Ceramics

Abstract. Ba(Zn1/3Ta2/3)O3 dielectric materials were prepared by solid state reaction. The samples were sintered at temperatures in the range 1400±1600°C for 4 h. Morphostructural characterization was performed by using SEM and XRD. The dielectric properties were measured in the microwave range (6 ±7 GHz). An additional annealing at 1400°C for 10 hours was performed in order to improve the dielectric parameters. The best parameters were achieved for the samples sintered at 1600°C with additional thermal treatment.
