Abstract
In formation of an intermetallic compound from the elementary metals there is usually a contraction in volume. Electron transfer leading to the charge states M+ and M- with increase in valence and decrease in volume explains the more than 2-fold range in contraction for different compounds in the same binary system. In a more thorough analysis, the better packing of atoms of different sizes also needs to be considered.
Keywords: alloys, electron transfer in intermetallic compounds, hyperelectronic and hypoelectronic metals, buffer metals, tetrahedrally packed structures
