Niobium oxide (Nb 2 O 5) is generally the starting chemical for the production of other compounds, such as niobium chloride (NbCl 5 ), niobium carbide (NbC), or lithium niobate (LiNbO 3 ). Niobium metal is produced by the aluminothermic reduction of the oxide followed by electron beam refining. Niobium powders can be produced by the reduction ...

50%-70% of the world's tantalum is used to make tantalum capacitors in the form of capacitor-grade tantalum powder and tantalum wire. Since the surface of tantalum can form a dense and stable oxide film with high dielectric strength, it is easy to accurately and conveniently control the anodizing process of the capacitor.
