The lead-free BaTiO3 piezoceramic seems to be a potentially material replacing nowadays used PZT with some drawbacks in the processing and efficiency. The concept of co-sintered BaTiO3 piezo ceramic functional layers with protective ZrO2 and Al2O3 layers is based on strongly bonded layers (Gao, Xue, Liu, Zhou, & Ren, 2017; Zych, Wajler ...
Temperature dependences of the effective dielectric permittivity of pure BTO ceramics (blue curve) in comparison with that of Mn-doped samples.Much lower values of the permittivity in BTO-5Mn (black curve) and BTO-10Mn (red curve) are due to non-ferroelectric grains of the second phases.3.3.

High-performance BaTiO 3 (BTO)-based dielectric ceramics have great potential for high-power energy storage devices. However, its poor temperature reliability and stability due to its low Curie temperature impedes the development of most electronic applications. Herein, a series of BTO-based ceramics are designed and prepared on the basis of entropy engineering.
