Special Issue "Sintering and Grain Growth Behavior of Ceramics"
Deadline for manuscript submissions: 30 June 2020.
Sintering can be defined as the application of thermal energy to a shaped powder body to increase its strength by the formation of interparticle bonds and the elimination or control of porosity. Sintering is an essential step in the production of ceramics ranging from traditional applications such as porcelain and whitewares to high-performance applications such as bearings, microwave devices, fuel cells, capacitors, dental implants, and transducers. Although it is one of our oldest manufacturing technologies, sintering has only been studied scientifically since the 1940s. The two basic processes which take place during sintering are densification and grain growth. High density is desirable to improve the mechanical, electrical, and optical properties of ceramics. Grain size has a strong effect on the mechanical, electronic, magnetic, and optical properties of ceramics. Therefore, the control of both processes is vital in order to produce ceramics with the desired properties. This Special Issue will focus on sintering and grain growth behavior in ceramics, as well as on the relationship between microstructure and properties.
It is my pleasure to invite you to submit a manuscript to this Special Issue. I hope that this issue will gather together some of the latest and groundbreaking research on these topics. Manuscripts, both theoretical and experimental, concerning all types of sintering processes, ceramics, and applications are welcome. Full papers, communications, and reviews are all welcome.

Abstract: The market leading piezoelectric ceramics are, at the present moment, Pb(ZrxTi1-x)O3-based solid solutions. However, due to legislation and limitation of lead-based materials in commercial products , a big effort has-been put into study and development of more environmentally friendly alternatives. Sodium potassium niobate (KNN) based materials have been proved to be valid substitutes of lead-based piezoelectric ceramics. Construction of phase boundaries by chemical modification was proved to increase the piezoelectric activity with respect to pure KNN [2-4]. One of the approaches includes formation of solid solutions of KNN-based formulations with alkaline-earth perovskites, such as CaZrO3 (CZ) [5-6]. Moreover, NaNbO3 (NN), one of the end-members of KNN solid solution, is a prototype lead-free antiferroelectric, however, trace impurities or low applied electric fields may induce ferroelectricity. It has been shown that forming solid solutions of NN with CZ can be a strategy to stabilize the antiferroelectricity . Such materials could then be used in energy storage. In the present study, we primarily focus on the microstructure, domain configuration and domain structure of selected alkaline niobate based solid solutions. Both Li,Ta and Mn-doped KNN-based solid solution with CZ, as a representative lead-free piezoceramic, and NN-CZ solid solution as a lead-free antiferroelectric are considered.
