Abstract :
Ceramic based Ba(Zn1/3Ta2/3)O3 materials were prepared by solid-state reaction. Studies on microwave dielectric parameters in correlation with structural and Raman investigations were performed. Sintering temperatures higher than 1600degC are required in order to obtain dielectric properties suitable for millimeter wave applications.
