2019-6-28 · A high k usually is desirable for efficient energy conversion, but k does not account for dielectric losses or mechanical losses, nor for recovery of unconverted energy. The accurate measure of efficiency is the ratio of converted, useable energy delivered by the piezoelectric element to the total energy taken up by the element.

Lead-free Dielectric and Piezoelectric Ceramics - …

A goal in the search for lead-free piezoelectrics is to discover solid solutions with temperature insensitive morphotropic phase boundaries, as this is likely to enhance piezoelectric properties and promote temperature-stability. Furthermore, there is a high drive for developments of temperature stable dielectric ceramics which can operate at temperatures > 200 ºC, well above the limit of

Effect of MgO addition on sintering temperature, …

Abstract. MgO addition Ba(Zr 0.15 Ti 0.85)O 3 (BZT) ceramics was prepared using conventional solid state reaction method and effect the MgO content in BZT ceramics on their sintering temperature, microscopic appearance, dielectric properties and ferroelectric properties was investigated. The result is that the addition of MgO can greatly reduce the sintering temperature of BZT ceramics.
