The rare earth elements (REE) are 15 elements with atomic no. 57 through 71, from lanthanum to lutetium, plus yttrium. Although industrial demand for these elements is relatively small in tonnage terms, they are essential for a diverse and expanding array of high-tech applications. REE-containing magnets, metal alloys for batteries and lightweight structures, and phosphors are essential for many current and emerging alternative energy technologies, such as electric vehicles, energy-efficient lighting, and wind power.
