  • Impact of Ferroelectricity
    erroelectric materials are ubiq- Fuitous in electrical and elec- tromechanical components and systems. Ferroelectricity is associated with large dielectric and piezoelectric coefficients, particularly when the composition is adjusted to position the solid near a phase boundary. This characteristic allows high volumetric efficiency dielec- tric charge storage, as well as high dis- placement actuators at modest voltages. The ability to reorient the spontaneous polarization between crystallographically- defined states is essential in allowing poling of ceramic materials to obtain net Impact of piezoelectric or pyroelectric responses.

The poor availability of mica- based crystals during World War II spurred development of By Susan Trolier-McKinstry air- and moisture-stable, high volumetric efficiency dielec- trics.

  • Electroceramics XIII June, 24Th-27Th 2012 University of Twente, Enschede, the Netherlands
    Electroceramics XIII June, 24th-27th 2012 University of Twente, Enschede, The Netherlands Welcome It’s our pleasure to welcome you to the Electroceramics XIII conference, held in Enschede, the Netherlands, from June 24 – 27, 2012. We wish you a pleasant stay during the conference, which is hosted by the University of Twente. This booklet provides information about your participation in the scientific and social activities of the conference. The aim of this conference is to provide an interdisciplinary forum for researchers, theorists as well as experimentalist on the design, fabrication, theory, analysis and applications of functional materials and (epitaxial) thin films. Electroceramics materials and applications thereof have become an important field of research within materials science. Major breakthroughs in the synthesis of electroceramic materials, in bulk and (epitaxial) thin films, as well as the understanding of the structure-property relation of these materials have been realized in the last decades. This has led to many exciting new concepts, which are nowadays used in many technological applications. The series of Electroceramics conferences have become an important forum to discuss recent advances and emerging trends in this developing field. New research areas have been adopted, such as the epitaxial thin film research, and it is the aim to further develop the field by adopting other interesting research fields. We hope that you will enjoy the presentations and will also take the opportunity to attend the conference reception and banquet. On behalf of the international advisory board, the national organizing committee, the local organizing committee, and the many volunteers —Welcome to the University of Twente, Enschede.

I will endeavor to not go over the allocated total time so that the online version does not end up being more work than an in-person class. This means that our Zoom discussions will not typically take up the full 9:00-9:50 AM slot. Discussions on Zoom will include: answering your questions about lecture content, summarizing the important points, presenting case studies and real-world examples of the material from lectures (e.g., news/research highlights or example questions), and student presentations. The purpose of discussions is like office hours: to help you understand and apply the lecture material and connect it to relevant applications.

  • Barium Titanate and Barium Strontium Titanate Thin Films Were Deposited on Base Metal Foils Via Chemical Solution Deposition and Radio Frequency Magnetron Sputtering
    ABSTRACT AYGÜN, SEYMEN MURAT. Processing Science of Barium Titanate. (Under the direction of Jon-Paul Maria.) Barium titanate and barium strontium titanate thin films were deposited on base metal foils via chemical solution deposition and radio frequency magnetron sputtering. The films were processed at elevated temperatures for densification and crystallization. Two unifying research goals underpin all experiments: 1) To improve our fundamental understanding of complex oxide processing science, and 2) to translate those improvements into materials with superior structural and electrical properties. The relationships linking dielectric response, grain size, and thermal budget for sputtered barium strontium titanate were illustrated. (Ba0.6Sr0.4)TiO3 films were sputtered on nickel foils at temperatures ranging between 100-400 °C. After the top electrode deposition, the films were co-fired at 900 °C for densification and crystallization. The dielectric properties were observed to improve with increasing sputter temperature reaching a permittivity of 1800, a tunability of 10:1, and a loss tangent of less than 0.015 for the sample sputtered at 400 °C. The data can be understood using a brick wall model incorporating a high permittivity grain interior with low permittivity grain boundary. However, this high permittivity value was achieved at a grain size of 80 nm, which is typically associated with strong suppression of the dielectric response. These results clearly show that conventional models that parameterize permittivity with crystal diameter or film thickness alone are insufficiently sophisticated. Better models are needed that incorporate the influence of microstructure and crystal structure. This thesis next explores the ability to tune microstructure and properties of chemically solution deposited BaTiO3 thin films by modulation of heat treatment thermal profiles and firing atmosphere composition.

  • I Ceramic Material Classes
    I Ceramic Material Classes Ceramics Science and Technology Volume 2: Properties. Edited by Ralf Riedel and I-Wei Chen Copyright Ó 2010 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim ISBN: 978-3-527-31156-9 j3 1 Ceramic Oxides Dušan Galusek and Katarína Ghillanyova 1.1 Introduction Ceramic oxides represent the most extensive group of ceramic materials produced today. Traditionally, but rather artificially, the oxide ceramics are divided into traditional and advanced groups. The traditional ceramics include mostly silica-based products prepared from natural raw materials (clays), including building parts (bricks, tiles), pottery, sanitary ware, and porcelain, but also ceramics with other main components (e.g., alumina, magnesia), which are applied in the field of electroceramics (insulators), or industrial refractories. Advanced ceramics require a much higher quality and purity of raw materials, as well as the careful control of processing conditions and of the materials micro- structure. They usually comprise oxides, which do not quite fall within the traditional understanding of the term silicate materials and ceramics. Oxides found in these ceramics include mostly oxides of metals such as aluminum, zirconium, titanium, and rare earth elements. Originally investigated mainly as materials for structural applications (especially alumina and zirconia), ceramic materials (and not only oxides) partly failed to meet the expectations, mainly due to problems with reliability and high production costs. In recent years, therefore, a significant shift has been observed in pursuing and utilizing the functional properties of ceramic materials, especially chemical (high inertness), optical, electrical, and magnetic properties. Another area of research which has been pursued in recent years is the refinement of microstructure to the nanolevel.

A maximum in dielectric and piezoelectric response is observed near the morphotropic phase boundary (MPB) separating rhombohedral and tetragonal ferroelectric phases. The origin of the enhanced properties near the MPB remains controversial and has been variously attributed to coexisting rhombohedral and tetragonal ferroelectric phases, to the formation of nanodomains, and/or to lower symmetry monoclinic phases. Hence, the phase diagram of PZT in the region of the MPB remains open to debate. In this work, dense polycrystalline PZT ceramics prepared by chemical methods were subjected to different time-temperature histories to investigate the origins of the two-phase coexistence and to determine the influence of thermal history on structure, microstructure and dielectric properties. Long annealing (240 hours) above the Curie temperature (Tc) revealed a slow relaxation process that was manifested in changes of structural properties. The changes in structural properties were accompanied by changes in the behavior of the paraelectric to ferroelectric phase transition, the domain structure, and the extrinsic contributions to dielectric permittivity.
