Analysis:

Product Details:

It’s a blue- gray, shiny, heavy, ductile, hard and a good conductor of electricity and heat dark metal. Tantalum is extracted from an ore called coltan (columbite and tantalite composed). Tantalite has properties that have contributed to the progress of the electronic industry: it has high conductivity, has refractive power (high temperature resistant), temporarily stores electrical charge and releases it when needed and also resists corrosion. The Oreization of Ta and Nb economically most valuable and important are the tantalite – compound of tantalum oxide, iron and manganese [(Fe, Mn Ta2O6] – and columbite – compound niobium oxide, iron and manganese [(Fe, Mn) Nb2O6]. For these reasons coltan is essential for the production and miniaturization of capacitors for mobile phones, computers, monitors, GPS systems, satellite guided weapons or material.
