Abstract
To develop low-temperature-fired BaTiO 3-based ceramics, the effects of various glasses (BaO–B 2O 3–SiO 2 (BBS), PbO–B 2O 3–SiO 2 (PBS), and ZnO–B 2O 3–SiO 2 (ZBS1: 57 mol%ZnO–33 mol%B 2O 3–10 mol%SiO 2 and ZBS2: 60.7 mol%ZnO–24.9 mol%B 2O 3–14.4 mol%SiO 2)) addition on both the sintering behavior and dielectric properties of BaTiO 3 were investigated. X-ray diffractometer (XRD), scanning electron microscopy (SEM), dilatometer were used to examine the effect of various glasses on the densification of BaTiO 3 and the chemical reaction between the glass and BaTiO 3. The results indicate that ZBS2 glass can be used as a sintering aid to reduce the sintering temperature of BaTiO 3 from 1300 °C to 900 °C without the formation of secondary phase. The dielectric properties of BaTiO 3 with ZBS2 glass sintered at 900 °C show a relative density of 95%, a high dielectric constant of 994, and a dielectric loss of 1.6%.
