Barium Sulfide - an overview | ScienceDirect Topics

The reduction of barium by silicon from Fe-75% Si could be described as 2BaO + [Si] FeSi = [BaSi] + (2BaO·SiO 2). This process produces FeSiBa alloy with up to 25% barium, and it is also possible to make aplex alloy containing both Ba and Ca. Melting is carried out in a batch process in an electric arc furnace.
