Notes:
Multilayered BaTi1-xSnxO3 (BTS) ceramics with different Ti/Sn ratios were produced bypressing and sintering at 1420 oC for 2 hours. X-ray diffractometry, scanning electron microscopy andenergy dispersive spectroscopy were used for structural, microstructural and elemental analysis,respectively. The dielectric and ferroelectric behavior of sintered samples was studied, too. It is foundthat in ingredient materials, with increasing Sn content, the tetragonality decreases; Curietemperature moves towards room temperature, while the maximum of the dielectric constantincreases, and also, they becomes less hysteretic. It is noticed that multilayered BTS ceramics withdifferent Ti/Sn contents have a broad transition temperature and show a relatively high dielectricconstant in a wide temperature range. It is shown that dielectric properties of these materials may bemodified by a combination of different BTS powders as well as layers number
