Analysis of phase equilibria in the Ni-C-O, Ni-Ca-O and Ni-AI-0 systems in condition of existence of nickel melt

Using the thermodynamic calculations, the surfaces of components solubility in metal melt for the Ni-C-O, Ni-Ca-O and Ni-Al-O systems were plotted. The surfaces plotted can be used for analysis of technological processes related to interaction of oxygen, carbon, calcium and aluminium in nickel melt.
