Influence of barium titanate content and particle size on electromechanical coupling coefficient of lead-free piezoelectric ceramic-Portland cement composites

Acoustic and electrical properties of 1–3 connectivity bismuth sodium titanate–Portland cement composites

“…The results of this work indicate that the acoustic impedance of lead free piezoelectric ceramic-Portland cement composites can be matched with concrete [16][17][18][19]. Moreover, the piezoelectric properties of lead free piezoelectric ceramic-Portland cement composites fabricated with 1-3 connectivity have shown that the piezoelectric and electromechanical properties of composites are better than those of composites fabricated with 0-3 connectivity [15][16][17][18][19].…”

“…In our previous work [15][16][17][18][19], we investigated the piezoelectric properties of lead-free piezoelectric ceramic-Portland cement composites consisting of lead free piezoelelctric materials, e.g., barium titanate (BT) and barium zirconate titanate (BZT). The results of this work indicate that the acoustic impedance of lead free piezoelectric ceramic-Portland cement composites can be matched with concrete [16][17][18][19].…”

Micro-scaled size-dependence of the effective properties of 0–3 PZT–cement composites: Experiments and modeling

“…In the next section, we will adopt a recently developed micromechanics model [32] to predict this particular phenomenon by taking the imperfect interfaces into consideration. The imperfection of interfaces between the PZT particles and the Table 1 A summary of size-effect study on Portland cement-based piezoelectric composites (particle volume = 50%) [20][21][22][23][24].…”

“…Note that the effect of particle size on the acoustic impedance has also been studied in Ref. [24], while that on the instantaneous remnant polarization and instantaneous coercive field has been reported in Ref. [25].…”

“…They found that, under the condition of the same PLN content and fabrication technique, both the piezoelectric strain factor d 33 and the piezoelectric voltage factor g 33 increase with the PLN particle size; but when the PLN particle size is larger than 100 lm, they become hardly influenced by the PLN particle size. The research group led by Chaipanich [20][21][22][23][24] has conducted a comprehensive study on the size-effect in piezoelectric strain factor d 33 composites, and their results have been summarized in Table 1 for future reference. Note that the effect of particle size on the acoustic impedance has also been studied in Ref.…”
