The first characterization of the microwave dielectric properties of the La 3 Ti 2 TaO 11 ceramics is presented. An ordinarily sintered ceramic at 1560 • C exhibits good microwave dielectric properties with ε r = 46, Q × f = 7500 GHz and τ f = −47 ppm/ • C. An alternative approach to tailor the temperature coefficient of resonate frequency of La 3 Ti 2 TaO 11 ceramics is also presented. Textured La 3 Ti 2 TaO 11 ceramics were fabricated using spark plasma sintering (SPS). By controlling the sintering temperature, orientation degree increased together with the steadily increase in ε r and Q × f. A noteworthy change in τ f from −43.1 ppm/ • C to −13.6 ppm/ • C with increasing orientation degree was observed. These results suggest that grain-orientation control was an effective way to tailor the microwave dielectric properties of La 3 Ti 2 TaO 11 ceramics.
