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.
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.
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 .
Ytterby is the single richest source of elemental discoveries in the world; the chemical elements yttrium (Y), terbium (Tb), erbium (Er), and ytterbium (Yb) are all named after Ytterby, and five more elements were also first discovered there. Local roads connect Ytterby to county road 274 and hence the mainland.
Semiconductor applications dominate the commercial demand for gallium, accounting for 98% of the total. The next major application is for gadolinium gallium garnets. [72] As of 2022, 44% of world use went to light fixtures and 36% to integrated circuits, with smaller shares equal to ~7% going to photovoltaics and magnets each. [73]
