Piezoelectric and dielectric properties of transparent Pb(Ni1/3Nb2/3)1−x−yZrxTiyO3 ceramics prepared by hot isostatic pressing

摘要: Abstract The dielectric, pyroelectric, piezoelectric and optical properties of transparent Pb(Ni 1–3 Nb 2/3 ) 1− x − y Zr Ti O 3 (PNNZT) ceramics have been investigated. Hot isostatic pressing was used to achieve uniformly with transmittance more than 5% at 633 nm. room temperature dielectric constant 4200 a loss ∼0.025 were measured on these samples. Large electromechanical coupling factors, k p =69%, 31 =43%, t =56%, 33 ∼80%, large pyroelectric coefficients, 0.2075 μC/cm 2 K 2.3819 129°C, observed for poled ceramics. Transparent PNNZT could be promising candidates many applications such as electrooptics, pyrooptics, transducers/sensors.
