Influence of Thickness Parameters on 2-2 Cement Based Piezoelectric Composite

Abstract

2-2 cement based piezoelectric composite was fabricated using sulphoaluminate cement and lead magnesium niobate-lead zirconate-lead titanate ceramic (P(MN)ZT) by dice-and-fill technique. The effects of composite thickness on dielectric, piezoelectric and electromechanical properties of the composite were analyzed, respectively. The results show that the increase of composite thickness will improve the piezoelectric strain factor d33 of the composite, while decreases the piezoelectric voltage factor g33 of the composite. The relative dielectric factor εr as well as the dielectric loss tan δ of the composite also increases with increasing the thickness. The electromechanical analysis results show that the thickness electromechanical coupling coefficient Kt of the composite increases obviously with decreasing the thickness, meanwhile the mechanical quality factor Qm of the composite shows the increasing trend, thus, the receiving piezoelectric transducers can be fabricated by decreasing the thickness.

“…Investigation of the dielectric and acoustic impedance properties of 2-2 barium zirconate titanate-Portland cement composites reveals that the composites have higher piezoelectric voltage coefficients and lower acoustic impedance values than pure ceramic [ 9 ]. Cheng et al studied the effects of composite thickness on the dielectric, piezoelectric and electromechanical properties of the composite [ 10 ]. The receiving piezoelectric transducer can be fabricated by decreasing the thickness.…”
