Abstract

The microstructure of grain boundaries can be studied utilizing different techniques of TEM (diffraction contrast, high resolution TEM). Differences in the structures and geometries of the grain boundaries in ceramics (A12O3, SiC, Si3N4) are observed compared to metals.- The chemical compositions (of light elements up to Si) of layers close to the grain boundaries can be analysed by electron energy loss spectroscopy with a TEM fitted with a magnetic imaging filter. The lateral resolution for chemical analyses of this instrument is better than ~10nm. The variation of the chemical composition can be analysed qualitatively and quantitatively.
