Impedance characteristics and PTCR effect in lead free BaTi 1- x Sn x O 3 piezoceramics

Modification of structural, morphological, and dielectric properties of barium calcium titanate ceramics with yttrium addition

“…Among the several options considered, BCY 1.5 T exhibited the highest degree of insulation due to its pronounced elevation in the plotted line [ 60 ]. The BCY 1 T sample demonstrated a semicircular response when subjected to low frequencies, whereas at higher frequencies, it displayed a little curvature before transitioning into a linear behavior [ 61 ]. In contrast, BCY 1.5 T did not demonstrate semicircle behavior when subjected to low frequencies.…”

Electrocaloric Effect in Sn‐ and Y‐Codoped BaTiO3 Ceramics

“…Similar to the previous reports. [ 9,15,17,25 ] It was well known, the P – E loops greatly dependent on the microstructures. Usually, the larger grain size and higher density associate with larger polarization.…”

“…It was reported that Sn doping BaTiO 3 leads to T O–T and T C shift. [ 14–16 ] Sn‐doped (Na 0.5 Bi 0.5 )TiO 3 –BaTiO 3 presents tetragonal‐to‐cubic phase transition. [ 17 ] It was reported that Y doping lead to improved microstructure [ 10,18,19 ] and high polarization, [ 10,18 ] which are beneficial to the enhancement of ECE.…”

Toward a new PTCR material based on the Na2Ti6O13/Na2Ti3O7 system

“…Lakshmi K. et al found that BaTi1-xSnxO3 samples (x = 0.07, 0.08, 0.09, and 0.1) exhibited a PTCR effect above TC in a temperature range that varies with the composition. Here, the values corresponding to the jump provide one-order resistivities [28]. Liang Y. et al prepared Mndoped BNT-BT-based PTCR materials.…”
