Gadolinite

From Free net encyclopedia

Gadolinite is a mineral of a nearly black color and vitreous luster, and consisting principally of the silicates of cerium, lanthanum, neodymium, yttrium, beryllium, and iron with formula: (Ce,La,Nd,Y)₂FeBe₂Si₂O₁₀. Called gadolinite-(Ce) or gadolinite-(Y) depending on the prominence of the variable element composition.

Gadolinite was named in 1800 for Johan Gadolin, the Finnish mineralogist- chemist who first isolated an oxide of the rare earth element yttrium from the mineral in 1792. The rare earth gadolinium was also named for him. However, gadolinite does not contain more than trace amounts of gadolinium.
