Explanation: Tantalum metal element mainly exists in tantalite and co-exists with niobium. The texture of tantalum is very hard, the hardness can reach 6-6.5. Its melting point is as high as 2996℃, second only to tungsten and rhenium, ranking third. Tantalum is malleable and can be drawn into a thin wire-like foil. Its coefficient of thermal expansion is very small. It only expands by 6.6% per degree Celsius. In addition, its toughness is very strong, even better than copper. Tantalum also has extremely high corrosion resistance. It does not react to hydrochloric acid, concentrated nitric acid and "aqua regia" regardless of whether it is under cold or hot conditions.
Uses: It can be used to make evaporators, etc., and can also be used as electrodes for electron tubes, rectifiers, and electrolytic capacitors. Tantalum is easy to process and shape. It is used as support accessories, heat shields, heaters and heat sinks in high-temperature vacuum furnaces. It is medically used to make thin sheets or thin threads to repair damaged tissues.
