Neodymium: 1841 G. Mosander: 1885 C. A. von Welsbach: Discovered by Mosander and called didymium. Carl Auer von Welsbach later split it into two elements, praseodymium and neodymium. Neodymium had formed the greater part of the old didymium and received the prefix "neo-". [85] [125] 68 Erbium: 1843 G. Mosander: 1879 T. Cleve
A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. [1] They are the most widely used type of rare-earth magnet .
Auer von Welsbach's country house (Schloss Welsbach) in Mölbling, AustriaCarl Auer von Welsbach (1 September 1858 – 4 August 1929), [3] who received the Austrian noble title of Freiherr Auer von Welsbach in 1901, [4] [5] was an Austrian scientist and inventor, who separated didymium into the elements neodymium and praseodymium in 1885.
41 of the 118 known elements have names associated with, or specifically named for, places around the world or among astronomical objects. 32 of these have names tied to the places on Earth, and the other nine are named after to Solar System objects: helium for the Sun; tellurium for the Earth; selenium for the Moon; mercury (indirectly), uranium, neptunium and plutonium after their respective ...
Ancient people learned about magnetism from lodestones (or magnetite) which are naturally magnetized pieces of iron ore.The word magnet was adopted in Middle English from Latin magnetum "lodestone", ultimately from Greek μαγνῆτις [λίθος] (magnētis [lithos]) [1] meaning "[stone] from Magnesia", [2] a place in Anatolia where lodestones were found (today Manisa in modern-day Turkey).
All of the world's heavy rare earths (such as dysprosium) come from Chinese rare-earth sources such as the polymetallic Bayan Obo deposit. [ 44 ] [ 46 ] The Browns Range mine, located 160 km south east of Halls Creek in northern Western Australia , was under development in 2018 and is positioned to become the first significant dysprosium ...
This theory was proven right with the discovery of praseodymium and neodymium in 1885 by Carl Auer von Welsbach. In 1879, Cleve proved that the newly discovered element scandium was an element predicted by Dmitri Mendeleev to be "eka-boron". [1] He isolated a quantity of scandium in this same year and determined its atomic weight. [2]
