Abstract

The possibility of changing the thermodynamic properties of AlH ₃, alane, by fluorine anion substitution has been investigated by experimental measurements, ab initio calculations and thermodynamic modelling. No solid solution phases are observed experimentally. In accordance to this the calculations give a positive free energy of mixing for all compositions, showing that a mixed phase is not thermodynamically favourable. Thus fluorine anion substitution does not seem feasible for the alane system.
