Effect of dwell time during sintering on piezoelectric properties of (Ba0.85Ca0.15)(Ti0.90Zr0.10)O3 lead-free ceramics

Correlation of grain size, phase transition and piezoelectric properties in Ba0.85Ca0.15Ti0.90Zr0.10O3 ceramics

“…From then on, many modified BaTiO 3 -based lead-free piezoelectric ceramics (e.g., (Ba 1-x Ca x )(Ti 0.95 Zr 0.05 )O 3 [15], Ba(Zr 0.2 Ti 0.8 )O 3 -x(Ba 0.7 Ca 0.3 )TiO 3 [16], Ba(Zr 0.15 Ti 0.85 )O 3 -x(Ba 0.8 Ca 0.2 ) TiO 3 [17], (Ba 0.93 Ca 0.07 )(Ti 0.95 Zr 0.05 )O 3 [18], Pr 2 O 3 [19], ZnO [20], MnO 2 [21], CeO 2 [22] and La [23] doped Ba 0.85 Ca 0.15 Ti 0.90 Zr 0.10 O 3 , etc.) have been prepared and the effects of sintering methods [24], sintering temperature [25][26][27], dwell time during sintering [28], and poling conditions [29] on the piezoelectric properties of Ba 0.85-Ca 0.15 Ti 0.90 Zr 0.10 O 3 ceramics have been investigated. However, the correlation of grain size, phase transition and piezoelectric properties of Ba 0.85 Ca 0.15 Ti 0.90 Zr 0.10 O 3 ceramics has not been systematically investigated.…”

Enhancement of the temperature stabilities in yttrium doped (Ba0.99Ca0.01)(Ti0.98Zr0.02)O3 ceramics

“…Nevertheless, they are not environmental friendly for lead oxide toxicity. With the recent growing demand of global environmental protection, many researchers have greatly focused on lead-free ceramics to replace the lead-based ceramics [1][2][3][4][5][6].…”

Electrical properties and microwave dielectric behavior of holmium substituted barium zirconium titanate ceramics

“…BZT based ceramics with moderate dielectric constant and low dielectric loss have been obtained by manipulating the substitution amount of suitable rare earth ions up to 4% in A-and/or B-site [7][8][9]. Also, rare earth ions substitution in BZT with its improved dielectric and electrical behavior exhibit excellent piezoelectric behavior [10][11][12]. However, major concerns were on the solubility levels and the occupancy of the substituted rare earth ions in the BZT lattice.…”
