Ytterbium is a soft, malleable, and rather a flexible element with a brilliant silvery sheen. This rare-earth element is easily destroyed and dissolved by mineral acids, reacts slowly with water, and oxidizes in the air. The oxide forms a protective layer on the surface. Compounds of ytterbium are rare.
Ytterbium is sometimes associated with yttrium or other related elements and is used in some steels. Its metal can be used to improve grain refining, strength, and other mechanical properties of stainless steel. Several ytterbium alloys are used in dentistry. An isotope of ytterbium was used as a radiation source instead of a portable X-ray machine when electricity was not available. Like other rare earth, it can be used to bind phosphors, ceramic capacitors, and other electronic devices, and can even act as an industrial catalyst.
Ytterbium does not play a biological role, but its salts have been noted to stimulate metabolism. Ytterbium is irritating to the skin and eyes and is suspected of being a teratogen. All compounds should be stored in closed containers, protected from air and moisture, and handled as highly toxic.
Ytterbium metal dust is a fire and explosion hazard. Ytterbium poses no threat to plants and animals and its salts are introduced into the chemical industry as catalysts in place of those considered toxic and polluting.
