The early tantalum metal has more impurities. Werner von Bolton was first made of pure tantalum metal in 1903. Scientists first used the hierarchical crystallization method to extract tantalum from niobium. This method is found by de Marinella in 1866. Today, scientists are using a solvent extraction method for the solution containing fluoride.
Tantalum was discovered by Swedish chemist A.G. Ekeberg in 1802. It was named after the Greek mythology figure Tantalus. Tantalum is mainly present in tantalite and co-exists with niobium. Tantalum has moderate hardness and is full of ductility and can be drawn into filament thin foil.
