Did you know?
An intermediate phase
is a distinguishable homogeneous phase whose composition range does not
extend to any of the pure components of the system. Intermetallic compounds
are intermediate phases,
containing two or more metals, that usually have compositions, and specific crystal structures different from
those of the pure components of the system.
They generally have a very limited composition range, and often are described as "line compounds" because they
appear as vertical lines on the phase diagram.
The Ag-Sr diagram shown here has five
intermetallic compounds: SrAg5
, SrAg, and
, each of which has a specific, fixed composition. Of these intermetallic
compounds, only SrAg5
displays some solubility with the silver terminal solid solution.
Intermetallic compounds have unique melting points and therefore behave like pure elements.
