Bi2(Znl/3Nb2/3)2O7(β-BZN) materials, a kind of dielectric materials with a monoclinic pyrochlore structure, have been recognized as potential candidates low temperature co-fired ceramics (LTCC) microwave dielectric materials because of their relatively low sintering temperature and superior dielectric properties [1-3].
While Bi2(Mgl/3Nb2/3)2O7(β-BMN) materials with higher tunability than Bi2(Znl/3Nb2/3)2O7 materials was prepared by using Mg instead of volatile zinc[4~9].
Some study found that Bi2 (Mg1/3Nb2/3)2O7 materials has superior dielectric properties [10].
