Abstract:

The use of transmission electron microscopy for the study of a range of phenomena associated with the surfaces of ceramic materials is discussed. The approach used throughout the work described has been to prepare a thinned sample in a form suitable for imaging in the electron microscopy and then to modify the characteristics of this sample by heat treating it. The same sample is then used for further studies by depositing metallic or ceramic particles on the surface. The material systems illustrated include SiC and Al2O3 as the thin film with the particles being Cu, W, ThO2 or NiO.
