Abstract
Abstract Microwave ceramics of Ba4(Nd0.7Sm0.3)9.33Ti18O54 with 0–3 wt% Ag additions were synthesized by a citrate sol–gel method. The BaO–B2O3–SiO2 glass was also added into the sol–gel derived BNST ceramic powders as sintering aids. The undoped, Ag- and BaBS-doped samples can be sintered at 1250 °C, 1150 °C and 1000 °C, respectively. The microstructure and dielectric properties were then controlled by doping Ag or BaBS glass. Near isoaxial grains with about 250 nm and typical columnar grains were obtained for the silver-doped and BaBS-doped samples, respectively. For the
