Flash sintering of Perovskites

闪速烧结是一种致密化陶瓷的新途径。它利用额外的电压和电流来促进烧结过程。在这个项目中，我们将试图澄清外部电极的作用，解开不同的电荷载流子，试图了解磁力对致密化的影响，试图进一步了解闪光事件的起始阶段，建立一个整体的吉布斯自由能函数来描述这一过程，确定与传统烧结陶瓷相比功能陶瓷性质（铁电、磁性、磁电和半导体）的改变。尝试设计一种工业上适用的样品，了解复合绿体对Flash工艺的影响以及最终得到的结构和功能。磁场的附加影响将被研究。

Flash sintering is a novel route to densify ceramics. It utilizes additional electric voltage and current to foster the sintering process. In this project we will try to clarify the role of external electrodes, disentangle the different charge carriers, try to understand the influence of magnetic forces on densification, try to further understand the initiation phase of the Flash event, establish an overall Gibbs free energy function to describe the process, determine the modifications of functional ceramic properties (ferroelectric, magnetic, magnetoelectric and semiconducting) in comparison to classically sintered ceramics, try to devise an industrially applicable sample electroding and understand the influence of composite green bodies on the Flash process and their finally obtained structures and functionality. The additional influence of magentic fields will be investigated.
