Abstract

Abstract Colossal permittivity (CP) ceramics have a great potential in the development of miniaturization, integration and lightweight of electronic components. In this work, NdxSr1-xTiO3 (0.000 ≤ x ≤ 0.014) (NST) ceramics are successfully prepared via sintering in N2. Simultaneously microstructure and dielectric properties of NST ceramics are characterized. It can be found that 0.010 ≤ x ≤ 0.014 ceramics show CP (>20000, 20–1 × 106 Hz) and low dielectric loss ( T i T i ' , N d S r ⋅ , V O ⋅ ⋅ ) forms the defect dipoles ( Ti Ti ' − N d S r ⋅ , T i T i ' − V O ⋅ ⋅ − T i T i ' ) and the defect clusters ( V O ⋅ ⋅ − 3 T i T i ' − N d S r ⋅ ), which produces the electron pinning effect and restricts the long-range movement of the carriers. Additionally, the grain boundary with high insulation resistivity plays a major role in the resistance of ceramics, and it also acts as a high barrier layer to limit the movement of several delocalized carriers.
