Определение
A ductile malleable
gray element of the lanthanoid series of
metals. It occurs in association with other
lanthanoids in many minerals, including
monazite and bastnasite. The metal is reactive;
it reacts with water and tarnishes in
air. It is used in several alloys (especially
for lighter flints), as a catalyst, and in compound
form in carbon-arc searchlights,
etc., and in the glass industry.
