Niobium (or as some would call it columbium) is consumed mostly by the global steel industry in the form of ferro-niobium, which acts as a powerful alloy strengthener. Superalloys represent the other major end use for niobium. Niobium is primarily used in the manufacture of capacitors for the technology world. Next time you use your cell phone, or your iPod you are doing so thanks to niobium-based capacitors.
