Abstract
EPMA is frequently used to study the composition of high-temperature superconducting oxides. Typical applications are local analysis on polycristalline ceramics, small single crystals, and thin films deposited on a substrate. Besides of the metal components it is possible to determine oxygen quantitatively and, as it is demonstrated by bulk ceramic samples, in good agreement with thermogravimetric experiments. Experimental and theoretical aspects of EPMA applied to Y-Ba-Cu-O materials are discussed in respect of sensitivity, accuracy of quantitation, and the characterization of thin films having a thickness of less than 1 mym.
