Nuclear methods taking advantage of the selective interaction of energetic charged particles and ion beams with the different components of a ceramic compound and with impurity atoms are increasingly used to study surfaces and interfaces of ceramics. The methods most frequently used are Rutherford backscattering, with and without combination with the channelling effect, nuclear reactions, elastic recoil detection analysis, particle induced X-ray emission and high resolution alpha-spectroscopy. With a suitable selection of these methods, elements covering the full range from hydrogen to actinides and their gradients near interfaces can be measured easily and accurately. Examples for a number of different ceramics, from binary oxides, carbides and nitrides to complex oxides, are given. Impurity segregation, gradient formation by incongruent evaporation or preferential sputtering of light components, effects of interactions with aqueous solutions and of radiation damage are described in detail.
