Solubility of Ba in Liquid Iron and Interaction Effect of the Third Elements

Experiments were carried out at 1873 K in a double-temperature zone furnace using vapor pressure method. The equilibrium tests of barium vapor with liquid iron were conducted in CaO crucibles sealed in a Mo chamber. As a result, the experiments obtained the relation between the dissolved content of Ba in liquid iron and the vapor pressure of Ba and the standard Gibbs energies for the reactions Ba(g)=Ba and Ba(l)=Ba.
