This silvery-yellow metal is a highly reactive material that tarnishes rapidly under air, and its reaction with water changes proportionally with temperature. Neodymium is the second most abundant rare-earth metal behind cerium and exists in all kinds of lanthanide minerals. It is used in fluorescent lamps, energy-saving lamps, and colour televisions. When alloyed with iron and boron (NIB), it can produce outstanding permanent magnets, which are used in current car parts, loudspeakers, and computer data storage.
