Comprehensive optimization of piezoelectric coefficient and depolarization temperature in Mn-doped Bi0.5Na0.5TiO3-Bi0.5K0.5TiO3-BaTiO3 lead-free piezoceramics

Influence of MnO2 on the ferroelectric properties, energy storage efficiency and piezoelectric properties of high-temperature Bi3TaTiO9 ceramics

“…[28][29][30] A recent study found that adding 0.25 mol% MnO 2 to lead-free Bi 0.5 Na 0.5 TiO 3 -Bi 0.5 K 0.5 TiO 3 -BaTiO 3 piezoelectric ceramics increased their d 33 performance by 40%. 31 Parallel to this, Huajun, et al reported that doping MnO 2 improved the d 33 and electromechanical properties of Ba 0.98 Ca 0.02 Zr 0.02 Ti 0.98 O 3 . 32 According to Jun Sun et al doping of MnO 2 into barium titanate-based ceramics has improved the energy storage performance.…”
