Abstract
Ba0.75Sr0.25TiO3 (BST) and PbZr0.68Fe0.14Nb0.14Ti0.04O3 (PZFNT) ceramic
pellets were obtained by ceramic technology and their structural,
ferroelectric and pyroelectric properties were investigated. The relative
density of BST and PZFNT is about 93% and 90%, respectively, with an average
grain size of 102 ?m and 6.45 ?m. Both materials have similar room
temperature dielectric constants (~2000), but PZFNT shows higher remnant
polarization (~15?C/cm2) and better pyroelectric properties (~1.69?10?4
C/m2K), which recommend it for pyroelectric detectors, infrared radiation-
and laser pulse energy-meters.
