Ferroelectric and Dielectric Properties of La₂O₃-Doped BaTiO₃ Ceramics

Abstract:

The different concentration La₂O₃-doped BaTiO₃ ceramics were prepared by sol-gel method. The ferroelectric and dielectric properties of the ceramics are characterized by TF analyzer 2000. With the increased amount of La₂O₃-doped, the dielectric constant increase gradually, when the sintering temperature is 1250 °C, the dielectric constant has reached 4648 for La₂O₃ with 0.4％-doped. With the temperature increased the dielectric constant of La-BaTiO₃ increase gradually, when the sintering temperature is 1290 °C, the dielectric constant has reached 7066 for La₂O₃ with 0.4％-doped.
