Abstract
The solubility of hydrogen in liquid pure copper and several liquid binary copper alloys has been measured by the Sieverts’ method or the sampling method. The alloying elements, Ni, Co, Fe, Mn and Te increase the solubility while Sn, Zn, S, P and Sb decrease it. The standard free energy of solution of hydrogen in pure copper for the reaction
(Remark: Graphics omitted.)
in the temperature range of 1096° to 1288°C obtained by Sieverts’ method is given by
ΔG°=10800+7.51T cal/g-atomH.
