Chemical symbol Ta, a steel gray metal, belongs to the VB family in the periodic table. It has an atomic number of 73 and an atomic weight of 180.9479. It is a body centered cubic crystal with a common valence of+5. Tantalum has a lower hardness and is related to oxygen content. The Vickers hardness of ordinary pure tantalum in the annealed state is only 140HV. Its melting point is as high as 2995 ºC, ranking fifth among elemental substances, only after carbon, tungsten, rhenium, and osmium. Tantalum is highly ductile and can be drawn into thin foils in a wire like manner. Its coefficient of thermal expansion is very small. Each increase of one degree Celsius only expands by 6.6 parts per million. In addition, it has strong toughness and is even better than copper.
