A new ultra low loss microwave dielectric ceramic; Mg(Sn; 0.05Ti0.95)O3; (MSnT); was found and investigated. The compounds were prepared by the conventional solid-state route; and sintered at 1360-1480C for 2-6 h. The investigations show that the MgTi2O5 secondary phase was observed. Moreover; the dielectric properties were correlated with the formation second phase. The excellent microwave dielectric properties of Qf=322 000 (GHz); Εr=17.4; and τf=-54 ppm/°C were obtained from the new MSnT ceramics sintered at 1390C for 4 h. © 2009 The American Ceramic Society;
