Lanthanum is considered a rare earth metal because the process to mine it is difficult, time-consuming and expensive. Lanthanum is rarely the dominant lanthanide found in the rare earth minerals, and in their chemical formulae it is usually preceded by cerium. Rare examples of La-dominant minerals are monazite-(La) and lanthanite-(La).
Lanthanum is one of the rare chemicals, that can be found in houses in equipment such as colour televisions, fluorescent lamps, energy-saving lamps and glasses. All rare chemicals have comparable properties. La 2 O 2 is used to make special optical glasses (infrared adsorbing glass, camera and telescope lenses).
