The dielectric properties at microwave frequencies of Ba(Zn 1/3 Ta 2/3 )O 3 ceramics prepared by sintering were investigated. These ceramics had lower density but higher loss quality than ceramics hot‐pressed at 1400°C. Loss quality was greatly improved by prolonged sintering. The Q of the ceramics measured by the dielectric resonator method was 14 000 at 12 GHz. The ceramics were investigated by X‐ray diffraction analysis. It was found that Q improvement corresponds with increased Zn and Ta ordered structures in the ceramics.
