In this paper, barium and barium alloys have been studied theoretically. The feasibility of the refining effect and application of barium alloy deoxidation and desulfurization was discussed. The deoxidization and desulfurization capacity curves of two barium alloys, Si-Ba, Si-Ca-Ba, were measured by experiments.
