Applications of Chemical Microanalysis to the Study of Ferromagnetic and Ferroelectric Ceramics

摘要

With the development and perfection of Analytical Electron Microscopy in the last decade, AEM has found increasing application in the study of materials problems. Its application to the study of local chemistry in alloy systems has grown both in width as well as depth. Application of chemical microanalysis to structural ceramic materials has yielded much useful information on hitherto unresolved problems. In this paper, application of chemical microanalysis to the study of common materials science problems such as microsegregation, grain boundary precipitation, decomposition reaction, etc. in ceramic ferrites, garnets, and ferroelectric materials will be outlined with representative examples from the work done at Berkeley. In addition, the significance of these results with respect to the physical properties and processing of these materials are briefly discussed. The limitations and the difficulties involved in studying these materials will also be pointed out. (ERA citation 05:029353)
