Abstract

The kinetics of formation, phase stabilities, and dielectric constants of Pb(Li1/4Fe1/4W1/2)O3 and BaTiO3-added Pb(Li1/4Fe1/4W1/2)O3 have been compared. The addition of 2 mol% BaTiO3 in Pb(Li1/4Fe1/4W1/2)O3 was confirmed to promote the complete formation of the perovskite phase at 700 °C. Also, the thermal stability of the perovskite phase was significantly enhanced, which resulted in an increase of the dielectric permittivity.
