Noun
A rare metallic element, of uncertain identification, supposed to exist in certain minerals, as gadolinite and samarskite, with other rare ytterbium earth. Symbol Tr or Tb. Atomic weight 150.
Source: Webster's dictionaryIt is now thought that workers using double sodium or potassium sulfates to remove ceria from yttria inadvertently lost the terbium into the ceria-containing precipitate. Source: Internet
Small amounts of terbium occur in bastnäsite and monazite; when these are processed by solvent extraction to recover the valuable heavy lanthanides as samarium europium gadolinium concentrate, terbium is recovered therein. Source: Internet
Sodium terbium borate is used in solid state devices. Source: Internet
Terfenol-D is a terbium alloy that expands or contracts in the presence of a magnetic field. Source: Internet
The brilliant fluorescence allows terbium to be used as a probe in biochemistry, where it somewhat resembles calcium in its behavior. Source: Internet
The chromatographic separation behavior was then unknown for the element 97, but was anticipated by analogy with terbium (see elution curves). Source: Internet
