The effects of sintering temperature and poling condition on the piezoelectric properties of 0.935(Bi0.5Na0.5)TiO3 - 0.065BaTiO3 ceramics

Enhancing electromechanical properties of lead-free ferroelectrics with bilayer ceramic/ceramic composites

“…BNT-7BT, BNT-25ST, and bilayer samples were all sintered at 1150°C for 2 h. These sintering conditions were based on the investigation of Acosta et al [44]. Previous work has shown that minimal grain size and porosity of BNT-BT can be achieved by keeping the sintering temperature at the lower range of 1100°C to 1200°C [40], [45].…”

Optimization of sintering temperature for the enhancement of pyroelectric properties of lead-free 0.88(Na0.5Bi0.5)TiO3–0.084(K0.5Bi0.5)TiO3–0.036BaTiO3 piezoelectric ceramics

“…To the best of our knowledge, a systematic study of the effect of sintering temperature on the pyroelectric, figure of merit and ferroelectric properties of a ternary BNTBKT-BT system has not yet been reported, although studies of the effect of composition on piezoelectric, dielectric and ferroelectric properties have been conducted [33,35,38].…”

Structure and electrical properties of Bi1/2Na1/2TiO3-based lead-free piezoelectric ceramics

“…18 The composition x ¼ 0.065 for BNT-xBT ceramics belongs to the region of MPB, which has a relative high piezoelectric and ferroelectric properties. 19 However, the piezoelectric properties of BNT-BT system are not good enough for practical uses. In order to further enhance the properties of BNT-BT ceramics and meet the requirements for practical uses, it is necessary to develop new BNT-based ceramics.…”
