摘要：

BaTiO3-based ferroelectric glass-ceramics with the composition 0.65(Ba1-XSrX)TiO3.0.27SiO(2).0.08Al(2)O(3) (X = 0.2-0.6) were fabricated, and their tunable dielectric properties were measured at microwave frequency. Major crystalline phases that precipitated during thermal treatment up to 1000degreesC were (Ba,Sr)TiO3, Ba2TiSi2O8, and BaAl2Si2O8. The Curie temperatures of the heated bulk samples were successfully tuned near room temperature at the composition between X = 0.2 and 0.3. A thick-film sample with X = 0.3 showed 27% tunability at 5 GHz under 10 kV/cm bias voltage.
