Abstract:In this work, phase-pure Mg1.8(Ni1–x
Co
x
)0.2Al4Si5O18 (0 ≤ x ≤ 1) ceramics were synthesized by a high-temperature solid-state
method. On the basis of Rietveld refinement data of X-ray powder diffraction
and Phillips–Vechten–Levine theory, the atomic ionicity,
lattice energy, and bond energy of the compound were calculated to
explore their influence on the microwave dielectric properties of
ceramics. The Mg1.8Ni0.1Co0.1Al4Si5O18 (x = 0.5) ceramic
exhibited the best microwave dielectric properties: ε
