| Abstract: | Ba1-xZn1/3Nb2/3O3(x=0~0.02) ceramics were prepared by the solid-state reaction. The effects of Ba deficiency on phase compositions, long rang order (LRO) of B-site ions and microwave dielectric properties of Ba1-xZn1/3Nb2/3O3ceramics were investigated. The X-ray diffraction(XRD) reveals that moderate Ba deficiency can increase the degree of LRO, while the highest degree of LRO is obtained for the sample with x=0.01. Furthermore, Ba deficiency can effectively improve the sinterability, density and Q f value ... |
