Abstract
Assuming that the liquid state of copper is quasicrystalline and the gas atoms dissolved are situated interstitially in the vacant positions of the lattice, the theoretical formulae on the equilibrium between H2S-H2 gas mixture and sulphur in molten copper has been derived by the statistical thermodynamical method. Next, for comparing with the experimental data obtained by the author, the values of some unknown constants ΨS, \varphiSS, θS in theoretical formulae, which correspond to the interaction energy between S-Cu and S-S pairs and the vibrational characteristic temperature of sulphur atom in molten copper have been determined numerically. So, when these values are substituted into the theoretical formulae, the following semi-theoretical equations can be obtained:(This article is not displayable. Please see full text pdf.) \ oindentin which, x and y are the atomic concentration of sulphur and hydrogen in molten copper respectively.
