Thermodynamic modeling of the borbarium ferroalloy smelting technological process

Abstract

A complete thermodynamic modeling of chemical transformations during carbothermic reduction of barium and boron from oxides has been performed. It was shown that during the processing of charge with a high BaO: BaO:B2O3(3:1), barium carbide (BaC2), iron boride (FeB), and barium hexaboride (BaB6) are present as phase components in the smelting products, with the former predominantly noticeable. The data obtained allow us to conclude that it is possible to produce a new ferroalloy containing boron and barium.
