Metal tantalum

Technical Characteristics

Ta is the 73rd element in the Mendeleev's chemical table/ Due to the presence of surface oxides, this metal has a steel-gray color with a bluish cast. Until 1844 it could not be separated from niobium and was considered as one metal, which was called columbium. The refractory metal tantalum has a number of excellent qualities (heat resistance, hardness, ductility). It is also chemically inert and is not subject to oxidation under normal conditions. Its main parameters:

  • atomic mass - 181 g/mol;
  • melting point - 2996 ° C;
  • melting point - 24.7 kJ/kg.

The most common alloys of tantalum with niobium, tungsten and molybdenum. They have proven excellent in the production of various types of special steels:

  • corrosion-resistant;
  • structural;
  • high-precision steels.

The metal tantalum has a valuable combination of high emissivity and heat resistance. It readily absorbs gases to maintain vacuum in electrovacuum devices. Tantalum coatings are as aesthetically pleasing and durable as those made of chromium or nickel. Methods have been developed for coating large items (pipes, crucibles, sheets, rocket nozzles) with tantalum, and the coating can be applied to different materials such as steel, copper, and graphite. Interestingly, the strength of the coating exceeds the strength of technical tantalum by more than 3 times. This metal is alloyed into high-temperature resistant stainless pipes for the needs of nuclear power engineering and petrochemistry, nozzles for artificial silk manufacture.
