A close relation between thermal data and the thermodynamic stability of intermetallic compounds is pointed out. Several series of intermediate phases formed by metals of theA and transition groups with elements of groups IB to IVB have been considered. The dependence of the thermal and thermodynamic stabilities on the atomic size, the electronic configuration, the electronegativity and the melting temperature of the component is discussed.
