lanthanides (rare earth)click to hear

Very reactant elements found in the lanthanide series (monazite, xenotime); some are relatively abundant in the Earth’s crust.
lanthanides (rare earth) erbium ytterbium thulium lutetium dysprosium holmium terbium samarium promethium neodymium praseodymium cerium gadolinium europium lanthanum

erbium click to hear

Metal that is used mainly in some alloys (especially with vanadium), lasers and infrared-absorbing glass, and as a colorant for glass and enamel.

ytterbium click to hear

Metal that is used in the manufacture of stainless steel, in lasers and as a source of X-rays in portable radiology equipment.

thulium click to hear

The rarest of the lanthanide group; it is used as a source of X-rays in portable radiology equipment and in the manufacture of ferrites (magnetic ceramics).

lutetium click to hear

Very rare metal that is difficult to separate; it has no real industrial applications but can be used as a catalyst (cracking, hydrogenation).

dysprosium click to hear

Very rare metal that is used especially in permanent magnets, lasers and nuclear reactors (absorbing neutrons).

holmium click to hear

Very rare metal with limited applications; it is used in lasers and for coloring glass.

terbium click to hear

Rare metal that is used especially in lasers and semiconductors.

samarium click to hear

Rare radioactive metal that is used especially in optical glass, lasers, nuclear reactors (absorbing neutrons) and permanent magnets.

promethium click to hear

Radioactive metal that is used mainly in specialized batteries and luminescent coatings for watches, and as a source of X-rays in medicine.

neodymium click to hear

One of the most reactant of rare metals; it is used mainly to manufacture lasers, eyeglasses and permanent-magnet alloys.

praseodymium click to hear

Metal that is used especially in protective lenses, colorants for glass, flint alloys (misch metal) and permanent magnets.

cerium click to hear

The most common metal of the lanthanide group and the main constituent of flint alloys (misch metal).

gadolinium click to hear

Metal that is often alloyed with chromed steel; it is used especially in the manufacture of permanent magnets, magnetic heads and electronic components.

europium click to hear

The most reactant metal of the lanthanide group; it is used especially in television screens (the color orange) and nuclear reactors (absorbing neutrons).

lanthanum click to hear

Metal that reacts with water to yield hydrogen; it is used especially in flint alloys and optical glass.
