Influence of Grain-Growth Inhibitors on Modified (Ba,Sr)(Sn,Ti)O for Electrocaloric Application.

The paper reports on effect of grain-growth inhibitors MgO, YO and MnCO as well as Ca modification on the microstructure, dielectric, ferroelectric and electrocaloric (EC) properties of BaSrSnTiO (BSSnT). Furthermore, the effects of the sintering time and temperature on the microstructure and the electrical properties of the most promising material system BaCaSrSnTiO (BCSSnT-20) are investigated. Additions of MgO ( = 1%), YO ( = 0.
