Kurzbeschreibung (Abstract)
(1-x)(Ba0.9Ca0.1)TiO3-xBa(Sn0.2Ti0.8)O3 ceramics x = 0, 0.4, 0.5 and 0.6 were synthesized. With Sn addition, orthorhombic to tetragonal transition temperature increased to higher temperature side and tetragonal to cubic transition temperature reduced towards room temperature for x = 0.4 and x = 0.5 and all phase transitions merged into one for x = 0.6. Multiple heating-cooling cycles' measurement of pyroelectric current was carried out over an excursion of temperature relevant to the pyroelectric applications. The pyroelectric coefficient increased from 1 × 10−4C/m2.K (x = 0) to 2.05 × 10−4C/m2.K (x = 0.4) sample at 303 K. Such enhancements could prove to be advantageous in deriving pyroelectric figures of merit. © 2017 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
