Occasionally used for rare pieces of medical equipment or instruments as well. The only metal which burns in Nitrogen is Titanium. Applications. Tantalum was discovered by Anders G. Ekeberg in 1802, in Uppsala, Sweden, in the minerals tantalite from Finland and yttrotantalite from Sweden. Tantalum is a kind of refractory nonferrous metal with a hardness of 6-6.5. See more. It’s where tantalum and niobium come from The mineral coltan is one of the resources that is playing an important role in the technological revolution. Tantalum is a chemical element with symbol Ta and atomic number 73 in the periodic table. It is very inert and so useful in the chemical and nuclear industries to line reactors. Tantalum often plays the role of protecting other metals, whether the tantalum is used in a thin coating to protect its substrate from chemical attack, or as an additive in superalloys to improve their high-temperature performance. Tantalum is extensively used in products that require high reliability in extreme environments. Tantalum is largely corrosion resistant and used extensively to … More than 60 percent of this mined element is used to make capacitors for cellphones, pagers, personal computers, video cameras and automotive electronics. Tantalum is a very dense, malleable metal making it easy to work with similar to gold. According to the United States Geological Survey, tantalum's major use is in the production of electronic components. It has a high melting point and is frequently used as a substitute for platinum , which is more expensive. Tantalum is a shiny, silvery metal which is soft when is pure. Tantalum is found in a combination of rare minerals and is grey-white in color. Tantalum is naturally grayish in color with a hint of blue. Tantalum combines readily with other refractory metals, such as tungsten, to form alloys with high-temperature strength and stability. Tantalum is a blue-gray transition metal with element symbol Ta and atomic number 73. Tantalum (Ta) is an unsung hero in modern metallurgy.
