Tantalite is the most widespread tantalum mineral and makes for an important ore of the industrially useful metal. Tantalum is used in alloys for strength and higher melting points, in glass to increase the index of refraction, and in surgical steel, as it is nonreactive and nonirritating to body tissues.
Tantalum mineral concentrates may restrain from 2 to more than 5 dissimilar tantalumbearing minerals from the similar mining area. The trade of tantalum mineral concentrates is dependent on a certified examination for the tantalum oxide they enclose, with an assortment from .
The volumetric efficiency may turn out to be similar. Niobium caps, like tantalum, require a voltage derating for applications that involve current surges. The fate of niobium will probably depend most on user acceptance, which will rise and fall with the price of tantalum. The next step is the use niobium oxide, NbO, for the anode.
Tantalum is a small industry and has historically been susceptible to rapid changes in market balance with volatile price movements.
