High-Q microwave dielectrics in the (Mg1− x Zn x )4Ta2O9 ceramics.

Highlights: [•] Low-loss dielectrics (Mg1− x Zn x )4Ta2O9 (x =0.02–0.08) have been extensively investigated. [•] Formation of solid solution was confirmed by the XRD analysis and measured lattice parameters. [•] The ionic polarizabilities of the solid solutions were also obtained for the specimens. [•] The Q × f value can be promoted up to a value of 385,000GHz at x =0.05. [ABSTRACT FROM AUTHOR]
