✦ Synopsis


The mechanism of the formation of TlCl on solid Tl is shown to he similar to that on 40 at-% Tl amalgam. In both cases the initial reaction is the growth of a monomolecular layer of the new phase by the nucleation and expansion of two-dimensional centres. The significance of these observations is discussed.

In beiden Fiillen ist die erste Reaktion das Wachstum einer monomolekularen Schicht durch Keimbildung und Ausbreitung von zweidimensionalen Wachstumszentren.

Die Bedeutung dieser Beobachtungen wird diskutiert.
