Electroceramics span paraelectrics and polar dielectrics such as ferroelectrics and piezoelectrics (
Damjanovic, 1998;
Sebastian et al., 2015). Due to their versatile properties, dielectric ceramics are widely used in telecommunication (e.g., antenna), medical (e.g., sensors and transducers), aerospace (e.g., structural dielectrics) industries, and in almost all electronics (e.g., active and passive components) (
Nomura et al., 1994;
Abrar et al., 2004;
Reaney and Iddles, 2006;
Kandi et al., 2015). The compositions and processing methods fundamentally affect the performances of dielectric ceramics. For instance, the ceramic compound determines the dielectric, thermal and mechanical properties (
Sebastian et al., 2015). The processing method used to fabricate the ceramics significantly influence the microstructure and thus ferroelectric and piezoelectric properties (
Wang et al., 2018). The shaping procedure and sintering temperature also define the applicability, integration capabilities with other components, and cost of the ceramics. This research topic aims to update the research community in terms of the recent advancement of compositional and processing investigations, as well as their influence on relevant properties. In addition, it provides perspectives beyond conventional applications.
