| Abstract: | The influence of (Ca0.61Nd0.26)TiO3 on crystal structure and microwave dielectric properties of Ba4Sm9.33Ti18O54 was investigated by XRD and SEM. The results show that excellent microwave dielectric properties are achieved for some (1–x)Ba4Sm9.33Ti18O54-x(Ca0.61Nd0.26)TiO3 ceramics as following:εr=75, Q·f =8 985 GHz, τf =–8.2×10–6℃–1 for x = 0; εr =75, Q·f =9 552 GHz, τf =–14.4×10–6℃–1 for x = 0.2. |
