Gadolinium can be found in mines in the United States, China, and Brazil as well as in India, Australia, and Sri Lanka. About 400 metric tonnes of this chemical element are produced on an annual basis.
What is the history of gadolinium?
Gadolinium is named from the mineral gadolinite, in turn named forFinnish chemist and geologist Johan Gadolin.[3] In 1880, the Swisschemist Jean Charles Galissard de Marignac observed the spectroscopic lines from gadolinium in samples of gadolinite (which actually contains relatively little gadolinium, but enough to show a spectrum) and in the separate mineral cerite. The latter mineral proved to contain far more of the element with the new spectral line. De Marignac eventually separated a mineral oxide from cerite, which he realized was the oxide of this new element. He named the oxide "gadolinia". Because he realized that "gadolinia" was the oxide of a new element, he is credited with discovery of gadolinium. The French chemistPaul Émile Lecoq de Boisbaudran carried out the separation of gadolinium metal from gadolinia in 1886.
