15. Tantalum and niobium

Niobium and tantalum do not occur naturally as free metals. The charge to ionic ratio of tantalum and niobium results in strong bonds being formed with oxygen; in fact, most niobium–tantalum min-erals are oxides, rather than silicates, sulfides or phosphates. The most abundant niobium–tantalum minerals are listed in Table 15.2. The two most
