Product Detail:

Niobium is a gray and ductile metal, very similar to tantalum. It’s extracted from an ore called coltan (columbite and tantalite composed). The columbite – compound niobium oxide, iron and manganese [(Fe, Mn) Nb2O6] 98% of its reserves are in the state of Amazonas and Roraima. The Oreization of Ta an Nb economically most valuable and important are the tantalite – compound niobium oxide, iron and manganese [(Fe, Mn) Nb2O6]-. And if it’s the opposite it’s called Tantalite. The more niobium the mineral contains and the less tantalum, it is called Columbite-Tantalite or Ferrocolumbite-Tantalite, and the less niobium and the more tantalum it is called Tantalite. Columbite is common in nature forming elements are combined and Ores predominate over each other, as in this case. Columbite and tantalite, together with other Ores of tantalum and niobium carriers, they’re known informally by the abbreviation “coltan”; but if you want to accurately and appropriately refer to on this wealth, which has Venezuela, Brazil and Colombia, it’s necessary to start talking particularly of tantalum and niobium Oreization of these basic elements. Tantalum and niobium are refractory metals. They have a high melting point and withstand exceptionally high temperatures, 3017° C and 2468° C respectively. The heat resistence of Ta is twice the iron and is exceeded only by tungsten and rhenium; accordingly, the Ta and Nb have the potential to be used in high temperature resistant applications. Even, tantalum carbide (TaC) supports 3880°C and further has hardness similar to diamond. Nb and Ta are well known and no exists any mystery about them; appear bright gray color tending to turn blue when comes into contact with air; both belong to the goup of transition metals, have high density and weight, good ductility, are resistant to corrosion and superb thermal and electrical conductors. Thanks to its exceptional propierties, are currently used in the manufacture of high-tech components and super-strong metallurgical alloys.
