Tuning of dielectric, pyroelectric and ferroelectric properties of 0.715Bi0.5Na0.5TiO3-0.065BaTiO3-0.22SrTiO3 ceramic by internal clamping

Abstract: Influence of structural evolution on energy storage properties in Bi 0.5 Na 0.5 TiO 3 -SrTiO 3 -NaNbO 3 lead-free ferroelectric ceramics Journal of Applied Physics 121, 054103 (2017) This study systematically investigates the phenomenon of internal clamping in ferroelectric materials through the formation of glass-ceramic composites. Leadfree 0.715Bi 0.5 Na 0.5 TiO 3 −0.065BaTiO 3 −0.22SrTiO 3 (BNT-BT-ST) bulk ferroelectric ceramic was selected for the course of investigation. 3BaO − 3TiO 2 − B 2 O 3 (BTBO) gl… Show more

“…Table 2 also lists the p value (4.14 9 10 -4 C m -2°C-1 ) of a typical PZT ceramic measured at RT as a reference. The prepared NBT-0.06B 1?x T at x = 0.01-0.03 in this research show the comparable pyroelectric coefficients (3.30-3.5 9 10 -4 C m -2°C-1 ) [5,6,9].…”

“…There are several numbers of FOMs which are more appropriate to certain pyroelectric materials applications [6,27] and are derived from these application requirements. Pyroelectric coefficient (p) and the FOMs were analysed by using the following equations: [5,15,28] Ip ¼ pA dT dt ð1Þ…”

“…This may be linked to the microstructural change due to the change of the stoichiometric state of this composition. Composition B has a bigger c/a ratio than all other compositions ( Table 1), indicating that Composition B has more tetragonality in its structure than all other compositions [13,43,44,46,47]. Importantly, at RT, the p values for nonstoichiometry compositions are higher than that of PZT and other lead-free compositions (Table 2) [7,19,27,32].…”

“…This complex relationship between thermal (specific heat) and dielectric properties (dielectric constant and dielectric loss) helps in tuning the pyroelectric performance for device applications. The physical or chemical compositional modifications technique is one such method which has been adopted in the past to chemically tune their pyroelectric performance . The composites seem to be another solution to tune all physical properties as per requirements.…”
