Effects of Bi2O3 additive on sintering process and dielectric, ferroelectric, and piezoelectric properties of (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 lead-free piezoceramics

Electromechanical properties of Ce-doped (Ba0.85Ca0.15)(Zr0.1Ti0.9)O3 lead-free piezoceramics

“…Note that reduction of the sintering temperature, while keeping high piezoelectric properties, is highly desired from the industrial point of view [18]. In order to surmount this problem, a number of additives have been considered, among which CuO [21] and Bi 2 O 3 [22] were used to densify and lower the sintering temperature of BCZT ceramics. In addition, CeO 2 has been considered for lowering the sintering temperature and improving the small signal piezoelectric coefficients of BCZT [23][24][25], but no comprehensive studies of large signal piezoelectric properties, which are crucial for actuator applications, were reported.…”

Influence of K 0.5 Bi 0.5 TiO 3 on the structure, dielectric and ferroelectric properties of (Ba,Ca)(Zr,Ti)O 3 ceramics

“…Hayati [23] investigated the effect of bismuth oxide (melting point ~825ºC) on the sintering temperature of Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) ceramics. The results showed that the presence of 0.1 mol% Bi2O3 can allow the sintering temperature to be reduced from 1500ºC to 1350ºC.…”

Electrical and mechanical properties of BZT − xBCT lead‐free piezoceramics

“…10 The BCZT composition with piezoelectric coefficients higher than PZT-based ceramics (d 33 ≈ 620 pC/N for x = 0.5), 10 large blocking force values, 11 and high cycling stability 12 is a good candidate for actuator applications. 13 Despite its outstanding piezoelectric properties, BCZT suffers from some limitations, including high processing temperatures 14 and low T C , which limits the usable working temperature to less than 90°C. 15 The actuating process involves the intermittent domain switching in the ferroelectric phase of the piezoelectric material, which results in cyclic inelastic deformation and joule heating.…”
