Rare earths are chemical elements found in the Earth's crust. They are used in cars, consumer electronics, computers, communications, clean energy and defense systems. The big market for rare earths is magnets. In semiconductor production, rare earths are used in highk dielectrics, CMP slurries and other applications.
China produces more than 95% of rare earth elements, and produces about 76% of the world's total rareearth magnets. Bonded Ndmagnets are prepared by melt spinning a thin ribbon of the NdFeB alloy. The ribbon contains randomly oriented Nd 2 Fe 14 B nanoscale grains.
Rare Earth is an American rock band affiliated with Motown's Rare Earth record label (named after the band), which prospered from 1970–1972. Although not the first white band signed to Motown, Rare Earth was the first big hitmaking act signed by Motown that consisted only of white members.
