Gadolinium is a silvery-white metal when oxidation is removed. It is a malleable and ductile rare-earth element. Gadolinium reacts with atmospheric oxygen or moisture slowly to form a black coating. Gadolinium below its Curie point of 20 °C (68 °F) is ferromagnetic, with an attraction to a magnetic field higher than that of nickel.
Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of atomic number; [5] siderophiles shown in yellow Graphs of abundance against atomic number can reveal patterns relating abundance to stellar nucleosynthesis and geochemistry.
Today, the Indian and South African deposits still produce some rare-earth concentrates, but they were dwarfed by the scale of Chinese production. In 2017, China produced 81% of the world's rare-earth supply, mostly in Inner Mongolia , [ 8 ] [ 44 ] although it had only 36.7% of reserves.
Any rare-earth element can be used in a ReBCO; popular choices include yttrium (), lanthanum (), samarium (Sm123), [6] neodymium (Nd123 and Nd422), [7] gadolinium (Gd123) and europium (Eu123), [8] where the numbers among parenthesis indicate the molar ratio among rare-earth, barium and copper.
Gadolinite, sometimes known as ytterbite, is a silicate mineral consisting principally of the silicates of cerium, lanthanum, neodymium, yttrium, beryllium, and iron with the formula (Ce,La,Nd,Y) 2 FeBe 2 Si 2 O 10.
Gadolinium(III) oxide (archaically gadolinia) is an inorganic compound with the formula Gd 2 O 3. It is one of the most commonly available forms of the rare-earth element gadolinium , derivatives, of which are potential contrast agents for magnetic resonance imaging .
