Special Issue Information

Dear Colleagues,

Electroceramics include advanced ceramic materials that have interesting and useful electrical, optical, and magnetic properties that are applied in a wide variety of applications. Their unique properties have gained increasing importance in many technologies including communications, energy conversion and storage, electronics, and automation. This growing field includes dielectric, piezoelectric, ferroelectric, multiferroic, ionically conducting, semiconducting, and superconducting ceramics used in different domains such as consumer electronics, medicine and health, power engineering, or communication. Many of the electroceramic materials are inorganic solids (polycrystalline oxides) with potential electrical properties. Properties depend on the stoichiometry but also on the overall crystal and defect structures of the solids, as well as on interfacial effects. For this purpose, the preparation of the material using different synthesis methodologies, if this is possible at low temperatures, as well as the use of different techniques such as spark plasma sintering, flash sintering, or cold sintering, for its processing, is one of the most important aspects to obtain good materials and to find more advanced electroceramics. Thus, obtaining high-quality electroceramic materials involves being able to understand and optimise the composition–structure–property relationship.

This Special Issue will be an interesting interdisciplinary medium to collect research and contributions of recent advances, covering fundamental aspects of electroceramic materials: from synthesis and processing to properties. The recent advances included in this issue will be of interest to researchers and students working in this field. Therefore, I invite you to contribute papers in this growing and interesting area.

The preparation of solid electrolyte ceramic membranes is the object of intense study for its fundamental parts in the development of all solid-state batteries and improved battery separators. In this work, the procurement of large area solid electrolyte ceramic thick film membranes of the Li-NASICON Li1.3Al0.3Ti1.7(PO4)3 (LATP) composition is attempted. Through the use of LATP powders from a sol–gel reaction, a slurry is formulated and tape casted. The green tapes are sintered using two sintering times. In both cases, ceramic thick films of a 5.5 × 5.5 cm2 area and ≈250 µm average thickness were obtained. The characterization indicated almost pure phase samples with a bi-modal microstructure composed of large and smaller grains, being larger for longer sintering time. The samples are porous and brittle, presenting very high “bulk” conductivity but lower total direct current (DC) one, as compared with the commercial Li-NASICON (OHARA) thick films with a similar area. The larger the grains, the poorer the total conductivity and the mechanical properties of the thick-films. The formation of poorly adhering grain boundaries as the grain size grows is responsible for the worsened properties. A better control of the microstructure is mandatory. Full article
