Production of tantalum metal
Production
Everyone knows the expression "tantalum flour". It refers directly to the complex process of producing this metal. Industrial production of tantalum metal involves the reduction of high-purity oxides, chlorides, and fluoride salts. Typically, the main problem is separating the tantalum from the niobium and achieving a vacuum during processing, as tantalum readily absorbs gases. The production of tantalum metal begins with the beneficiation of an ore concentrate containing tantalum oxides and niobium in a ratio of about 1:8. The Nb+Ta mixture is separated by extraction, and in the next step the metal itself is refined and reduced with carbon. Tantalum bars, similar to other refractory metals, are produced by powder metallurgy by sintering metal powder. The processing is done in a vacuum arc furnace, plasma furnace or electron-beam furnace. Tantalum bar is a dimensional semi-finished product with the cross-section of 5-6 mm, which is subjected to further processing on rotary forging machines.
Advantages
It is a heat-resistant and refractory metal that is as hard and as malleable as gold. Its melting point is 2996 °C, boiling point is 5300 °C. Its density is 16.6 g/cm³, It is chemically inert, it does not react with molten alkali metals, with most acids and corrosive gases, but it does react. It is stable in air at normal temperature. Oxidation begins above 280 °C. Due to its high heat resistance, this metal is widely used by modern industry. With the advent of such new generation materials it became possible to improve many technological processes where the production involves the action of high temperatures and. aggressive environments. Thanks to these materials it became possible to ensure long-term reliable operation of the whole complex of equipment in a wide range of temperatures.
