Enhanced transduction coefficient and thermal stability of 0.75BiFeO3-0.25BaTiO3 ceramics for high temperature piezoelectric energy harvesters applications

Effect of frequency on the classical and relaxor ferroelectric behavior of substituted titanate Ba0.7Er0.16Ca0.05Ti0.91Sn0.09O3

“…Doping and substituting rare earths in BaTiO 3 have also generated a lot of attention due to its numerous applications. 16 To affect the ceramic's physical characteristics, such as grain growth and electrical resistance, trivalent rare earth ions can be sporadically replaced or doped. 17 Er 3+ ions are of considerable interest because of their potential influence on the physical properties of BaTiO 3 ceramics, including ferroelectricity, luminescence and energy conversion capabilities.…”
