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 µm and 6.45 µm. Both materials have similar room temperature dielectric constants (∼2000), but PZFNT shows higher remnant polarization (∼15 µC/cm2) and better pyroelectric properties (∼1.69 · 10−4 C/m2K), which recommend it for pyroelectric detectors, infrared radiation- and laser pulse energy-meters.
