Niobium (Nb), named after a greek mythology figure Niobe, is a gray-shining heavy metal. It is resistant to high acids and has properties similar to tantalum. The melting point is at 2.447°C. It is characterized by high heat resistance. Niobium and tantalum are together as ore and have to be separated by an industrial process. This is possible because both metals have a different solubility.
