Functional Electroceramics are among the most important functional materials and are indispensable for outstanding technological developments. They increasingly gain importance in digitisation and telecommunications as miniaturised electronic components, as electrode materials for batteries or fuel cells, or as actuators and sensors.
Piezoceramics especially have become a hot topic within the past decade. Legislations against the use of hazardous substances sparked research into environmentally friendly alternative materials. This has an extraordinary impact on research on lead-free piezoceramics. A wide range of new material systems was created or already known ones were rediscovered. The combination of already promising systems also led to promising results. In this way, new aspects were discovered that are important for other applications. These include extraordinary ion-conducting or semiconducting properties, as well as mechanical, electrical and structural processes under the influence of external stimuli. For materials science, these properties are of particular importance in connection with the transition from a fossil fuel-based society to the use of renewable energies. Together with the development of sophisticated characterisation methods, materials science in this field has made a great leap forward.
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

A review of recent advances in phase-field modeling of the domain structure evolution in ferroelectric nanoceramics

In this article we review recent advances in phase-field modeling of the domain structure evolution in nanocrystalline ferroelectric ceramics. We provide an overview of various phase-filed models that have been utilized on this topic and the latest progress made in this field. Among these studies, special attentions are given to the correlation between the microstructural dynamics within the material and the corresponding overall physical properties. On one hand, a ferroelectric nanoceramic consists of complex microstructures － the widely varying crystallographic textures, the diverse grain lattice orientations and the distinct local grain-boundary properties can directly influence the overall physical properties of the material. On the other, the microstructural characteristics are very likely to affect the domain structure dynamics, hence, the electromechanical behaviors of the ferroelectrics. These aspects are particularly worthy of investigation once the average size of the constituent grains reduces below several hundreds of nanometers. We shall feature several key factors that are correlated with the grain-size dependence of the material properties, and we shall summarize and demonstrate through a series of examples that one is able to discover the intrinsic and extrinsic role played by the microstructure of the nanoceramics with the phase-filed approaches.
