earth metals, consisting of those with atomic numbers between 57 and 63 and ytterbium, is often called the cerium metals. Misch metal is an alloy of the cerium metals often used in lighter flints, in alloys with other metals (especiallymagnesium), and to remove residual gases in the ...
Rare-earth element - Properties, Metals, Uses: As noted above, the rare-earth elements—especially the lanthanides—are quite similar. They occur together in nature, and their complete separations are difficult to achieve. However, there are some strikin
rare-earth metals, in chemistry, group of metals including those of the lanthanide series and actinide series and usually yttrium, sometimes scandium and thorium, and rarely zirconium. Promethium, which is not found in nature, is not usually considered
The rare earth elements (REEs) or rare earth metals (REMs) are a group of metals found within the same ores and possessing similar chemical properties. Scientists and engineers disagree on exactly which element should be included in a list of the rare earths, but they generally include the fi...

Rare Earth Metal Uses Unlike minor metals that saw a rapid boom post WWII, REMs did not have such an important role prior to 1965 even though minor amounts were produced. You may remember when the first color television sets appeared in the market, and you can thank Europium for that. Th...
