Ferroboron is produced economically for decades by the carbothermic process. However, the carbon content of ferroboron, is above 0.5 as a result of the carbothermic process, which adversely affects the properties of permanent magnets. On the other hand, the requirement of aluminium for reduction of iron ore in the aluminothermic process increases the production costs.
