Abstract
⺠Ba1âxCaxBi4Ti4O15 (0 â¤Â x â¤Â 1) ceramics with four-layer Aurivillius structure were fabricated. ⺠X-ray diffraction and Raman scattering techniques have been employed to probe into the structural changes on changing x. ⺠Curie temperature (TC) was found to increase with increase in Ca-doping whereas the diffuseness of phase transition decreased. ⺠Temperature coefficient of dielectric constant can be tuned over a wide range of temperature by changing Ca-content. ⺠Ferroelectric and piezoelectric properties are investigated.
