History

ParameterNeodymiumNiobium
HistoryThe element Neodymium was discovered by C. A. von Welsbach in year 1885 in Austria. Neodymium derived its name from the Greek neos didymos meaning 'new twin'.The element Niobium was discovered by C. Hatchett in year 1801 in United Kingdom. Niobium derived its name from Niobe, daughter of king Tantalus from Greek mythology.
