Thermodynamic Properties of B_2O_3-bearing Slags in Equilibrium with Fe-B-C_(satd). Alloys

摘要

Major natural B sources contain alkali or earth-alkali oxides bonded with water, like colemanite (2CaQ.3B_2O_3.5H_2O) and ulexite (Na_2O.2CaO.5B_2O_3.16H_2O). These minerals are treated with other minerals to give anhydrous borax (Na_2O.2B_2O_3) and boric acid which are then used in the production of boron chemicals, instead of being smelted directly. In recent years, due to the increase in demand for ferroboron, either a newer production method with higher output and efficiency, or an optimization of the existing technology became essential.
