N2 - Composite ceramics in a solid solution of Mg(Nb1-xTax)2O6 (x=0-0.09) were prepared by the mixed oxide route and their microwave dielectric properties have been investigated. Formation of solid solution was confirmed by the XRD, the EDX analysis and the measured lattice parameters. By increasing x, not only could the Q ́f of the Mg(Nb1-xTax)2O6 solid solution be tremendously boosted from 86,200 GHz at x=0 to a maximum 117,600 GHz at x=0.05, it also possessed the highest εr of 21.06. It was mainly a result of the uniform grain morphology and the highest relative density of the specimen. The composition anticipated to have a maximum Q́f (117,600 GHz at 9.97 GHz) is Mg(Nb1-xTax)2O6 with an εr ~21.06 and a τf ~ -62.7 ppm/°C.
