Physical and chemical properties:
chemical symbol TA, steel gray metal, belongs to VB group in the periodic table of elements, atomic number 73, atomic weight 180.9479, body centered cubic crystal, and the common valence is + 5. The hardness of tantalum is low and related to oxygen content. For ordinary pure tantalum, the Vickers hardness in annealed state is only 140hv. Its melting point is as high as 2995 ℃, ranking fifth among the simple substances, second only to carbon, tungsten, rhenium and osmium. Tantalum is malleable and can be pulled into thin wire foil. Its coefficient of thermal expansion is very small. It expands by only 6.6 parts per million for every one degree Celsius rise. In addition, it has strong toughness, which is even better than copper
Tantalum has a wide range of applications due to its characteristics. In the equipment for preparing various inorganic acids, tantalum can be used to replace stainless steel, and its service life can be dozens of times longer than that of stainless steel. In addition, in chemical, electronic, electrical and other industries, tantalum can replace the tasks that used to be undertaken by precious metal platinum, greatly reducing the cost. Tantalum is made into capacitors and used in military equipment
