A Numerical Expression for the P--C--T Properties of Metal Hydrides

A semiempirical equation for the equilibrium pressure--composition--temperature relations of metal hydride--hydrogen systems is presented. The P--C--T data are reduced using a free energy function RT ln(P/P sub xr ) where P sub xr is the pressure above a hydride with reference H content x sub r . Th...

Zusammenfassung:A semiempirical equation for the equilibrium pressure--composition--temperature relations of metal hydride--hydrogen systems is presented. The P--C--T data are reduced using a free energy function RT ln(P/P sub xr ) where P sub xr is the pressure above a hydride with reference H content x sub r . The experimental data collapse then into a single curve, to which the best fit of a Langmuir-like expression is calculated. 6 ref.--AA
