Microwave dielectric properties of high Q and temperature stable Li3(Mg1−xNix)2NbO6 ceramics

Crystal structure, densification, and microwave dielectric properties of Li3Mg2(Nb(1−x)Mox)O6+x/2 (0 ≤ x ≤ 0.08) ceramics

“…In fact, M. Castellanos et al had successfully synthesized Li 3 Mg 2 NbO 6 powders by solid‐state reaction in 1982, and the lattice parameters of obtained Li 3 Mg 2 NbO 6 powders were a = 8.552 Å, b = 5.897 Å, c = 17.721 Å. According to previous studies, the substitution of divalent ions (Zn 2+ , Ca 2+ , Ni 2+ , Co 2+ , Mn 2+ ) at Mg‐site of rock salt structured Li 3 Mg 2 NbO 6 ceramics have obviously improved the microwave dielectric properties, so did the substitution of pentavalent ions (Sb 5+ , V 5+ ) at Nb‐site . The improvement mentioned above might be related to the differences in the bond between cations and anions in different oxygen octahedrons.…”
