Cation disorder and phase transitions in the four-layer ferroelectric Aurivillius phases ABi4Ti4O15 (A=Ca, Sr, Ba, Pb)

Piezoelectric properties and thermal stabilities of strontium bismuth titanate (SrBi4Ti4O15)

“…Thermal annealing experiments were conducted by holding the poled samples at specific temperatures for 1 h. Finally, the thermal annealed sample was cooled to room temperature, and d 33 was subsequently measured. conform with the diffraction data of SBT [29], which confirms the presence of a single phase m=4 BLSF structure. The diffraction peak with the strongest intensity is the (119) peak, in good agreement with the intensity of the (112m+1) peaks observed in BLSFs [8][9][10][11][12][13][14][15][16][17][18][19][20].…”

Investigation of site selectivity of lanthanum in SrBi4Ti4O15 ceramic by structural, dielectric, ferroelectric and conduction behavior

“…2a. All the Raman modes correspond to the characteristic modes of SBT as reported earlier [26,27]. The low frequency modes are correlated with the motion of the heavier Bi 3?…”

Electrical properties of CaBi4Ti4O15–Bi4Ti3O12 piezoelectric ceramics

“…It is apparent that all diffraction peaks can be well indexed. As reported in former studies, CBT-BIT belongs to orthorhombic system with a space group of P2 1 am at room temperature [13], while BIT belongs to monoclinic system of B1a1 [18] and CBT belongs to orthorhombic system of A2 1 am [19].
