| Summary: | BiSmMoO<sub>6</sub> microwave ceramics were prepared by solid-phase reaction method using Bi<sub>2</sub>O<sub>3</sub>-Sm<sub>2</sub>O<sub>3</sub>-MoO<sub>3</sub> as raw materials. The rheological properties of the slurry and the microstructure and phase composition of the cast film were characterized. The results show that under the conditions of selecting the alcohol/isopropanol as the solvent, when pH=6 and the solid phase content is 60% (mass fraction, the same below), and with the additives of the slurry 2% tributyl phosphate dispersant, 8% PVB binder, and 4.8% polyethylene glycol plasticizer, the casting slurry has excellent rheological properties. After sintering, the cast film is dense in microstructure, and the phase composition does not change compared to the press-formed sample. |
