摘要：The sintering behavior and dielectric properties of Bi3+-substituted Nd(Zn0.5Ti0.5)O-3 (abbreviated as NZT) microwave ceramics (Nd1-xBix)(Zn0.5Ti0.5)O-3 (0 <= x <= 0.15) (abbreviated as NBZT) are investigated. XRD results reveal the formation of single perovskite solid solutions for x <= 0.05 samples. For x > 0.05 samples, pyrochlore phase begins to segregate from the perovskite phase and its volume fraction increases with x. B-site Zn2+/Ti4+ 1:1 long range order (LRO) is detected by Raman Spectroscopy. The degree of LRO varies as a function of sintering conditions and chemical composition. The microwave dielectric properties of the composition are measured. By substituting Bi3+ for Nd3+, the temperature coefficient of resonant frequency (tau(f)) tunes toward zero, however, the microwave quality factor, (Qf) deteriorates. For x = 0.03, tau(f) reaches a minimum value of 18.9 ppm/degrees C with relative permittivity of epsilon(r), = 48.2 and Qf = 1430 GHz, respectively. The effect of Bi-doping on the Qf value is discussed.
