lead titanates, frequency variations, dielectric constant, Curie temperatureAbstract
Owing to a wide range of applications, ferroelectric ceramics have remained the center of attention of researchers over a large period. With this perception, the present article reports the effects of the substitution of Ba2+ in lead titanate (PT) on its structural and electrical properties. X-ray diffractometry was employed for the phase confirmation and to reveal the crystallographic data. It authenticates the single-phase formation with a systematic decrease in the anisotropy. Typical X-ray diffraction data are refined, by using the Rietveld method. The substitution of Ba2+ in PT ceramics has caused a reduction in the ferroelectric Curie temperature and significant changes in dielectric properties.
