- Abstract
Well-densified Li3(Mg1−xZnx)2SbO6 (0.00 ≤ x ≤ 0.08) microwave dielectric ceramics were synthesized via a two-stage sintering process. The effects of Zn2+ substitution on the microstructure and microwave dielectric properties were investigated. All samples were identified as pure phase via the XRD detection. Remarkable microwave dielectric properties with a near-zero τf value were obtained in the Li3(Mg1−xZnx)2SbO6 (x = 0.04) sample sintered at 1325 °C for 5 h: εr = 7.8, Q × f = 97,719 GHz (13.4 GHz), τf = − 6 ppm/°C. The high Q × f value was related with the FWHM and grain size effect. All experimental results indicate that the Li3(Mg1−xZnx)2SbO6 ceramics are promising for 5G communication applications.
