Diffusion of the divalent impurities Mn2+, Ca2+, Cu2+, Fe2+, Co2+, Pb2+, Zn2+, Eu2+ and S2- in sodium chloride and other alkali halide crystals has been studied by electron microscopy and diffraction. At temperatures in the range 100°-700°C the impurities diffuse to the surface and form oxides which in some cases are epitaxial. This distribution of the impurities on the surface is studied and is found to have a strong influence on the overgrowth of other epitaxial deposits.
