MgZr0.85Sn0.15Nb2O8 ceramics with wolframite structure were synthesized through traditional solid-state reaction process. X-ray diffraction and scanning electron microscopy were used to analyze the phase and surface morphology. Bond ionicity, lattice energy and bond energy were calculated separately to investigate the correlations with microwave dielectric properties. Typically, optimal microwave dielectric properties were obtained at 1260 °C: εr = 24.91, Q × f = 94014 GHz, τf=− 43.93 ppm/oC.
