Abstract

The structural and microwave properties of Ba($Mg_{1/3}Ta_{2/3})O_3$-Ba($Co_{1/3}Nb_{2/3})O_3$ ceramics were investigated with composition ratio. The specimens were sintered at 1525$^{\circ}C$ for 5 hours in air. All specimens exhibited superlattice reflection planes of (100), (111), (200), (201), and (112). Increasing mole ratio of BCN ceramics, the peak intensity of superstructure reflection plane were decreased, while dielectric constant was slightly increased. The dielectric constant and quality factor of the 0.8BMT-0.2BCN ceramics were 27.51, 103,681 [at 1GHz], respectively.
