Electric field assisted sintering of gadolinium-doped ceria

Abstract

10 mol% Gadolinium-dotiertes Ceroxid (GDC10) ist ein Werkstoff von hoher technologischer Relevanz für eine potentielle Anwendung in elektrochemischen Zellen, Sauerstofftransportmembranen und Katalysatoren. Ein wesentlicher Nachteil ist jedoch, dass die Verarbeitung von GDC10 hohe Sintertemperaturen (1300°C-1600°C) mit Verweilzeiten von mehreren Stunden erfordert, um eine hohe relative Dichte (>96%) zu erreichen. Um das Sinterverhalten von GDC-Keramiken zu verbessern, ist eine grundlegende Untersuchung des Sinterverhaltens und eine Optimierung der Sinterparameter erforderlich. In dieser Dissertationsarbeit wurde der Einfluss von elektrischem Feld und Strom auf das Verdichtungsverhalten und die Mikrostrukturevolution von GDC10 untersucht. Weiterhin wurden die Optimierung der Sinterparameter für GDC10-Pulver und die Anpassung der Mikrostruktur durch Steuerung der Materialsynthese und der Verarbeitungsbedingungen untersucht.
