Next‐generation electronics and energy technologies can now be developed as a result of the design, discovery, and development of novel, environmental friendly lead (Pb)‐free ferroelectric materials with improved characteristics and performance. However, there have only been a few reports of such complex materials’ design with multi‐phase interfacial chemistry, which can facilitate enhanced properties...
Lead‐free Ba0.7Ca0.3Ti1−xSnxO3 (x=0.00, 0.025, 0.050, 0.075, and 0.1, abbreviated as BCST) electroceramic system was prepared by the solid‐state reaction method and its ferroelectric, piezoelectric, and electrostrictive properties were investigated. X‐ray diffraction shows that the compositions with x≤0.05 exhibit a tetragonal crystal structure having P4mm symmetry; while the compositions x=0.075...
The ferroelectric and piezoelectric properties of Sn4+ modified (Ba0.7Ca0.3)(Ti1−xSnx)O3, (with x = 0.000 to 0.100 in steps of 0.025) lead free electroceramics were investigated. With Sn4+ substitution, a structural phase transition from pure tetragonal to pseudo-cubic structure has been observed; which strongly influence the ferroelectric/ piezoelectric nature of the samples. At room temperature,...
