Kurzbeschreibung (Abstract)
We have synthesized Ba0.85Ca0.15Zr0.10Ti0.88Sn0.02O3 (BCZT-Sn)-cement composites.They were prepared as BCZT-Sn to cement ratios of 90–10% and 85–15% by weight. The larger fraction of BCZT-Sn ceramic was used to minimizethe losses in the composites. The open circuit voltage was found to be 0.75 V,0.56 V and 0.4 V for pure, 10% and 15% cement composites, respectively. The voltage and current were also measured across resistances of 1 and 3 MX, and the obtained voltages were lower for composites compared to pure BCZT-Sn. Nonetheless, they remain promising candidates over traditional pyroelectric materials for device applications owing to their advantages, such as (1) these composites can be made without any sintering process and (2) they can be made in any shape and size. We also studied relative permittivity, which influences performance of pyroelectric devices.
