Abstract:

A quasi-chemical model is presented and applied to the adsorption of tungsten on specific crystallographic planes of tungsten. The use of this method requires the assumption of a certain degree of recombination of electron orbitals from surface and subsurface atoms. A set of rules for recombination of bonding is presented and the results calculated using this method are in good agreement both with experimentally determined values of desorption enthalpies and with the tabulated enthalpy of sublimation for tungsten.
