Terbium

A soft, silvery-gray metallic element of the lanthanide series, extracted chiefly from the mineral monazite, used in high-temperature fuel cells as a stabilizer, in alloys responsive to a magnetic field, and in x-ray machines and lasers. Atomic number 65; atomic weight 158.925; melting point 1,356°C; boiling point 3,230°C; specific gravity 8.230; valence 3, 4. See Periodic Table.

Terbium

A rare metallic element, found in certain minerals, as gadolinite and samarskite, with other rare earths such as ytterbium. Symbol Tb. Atomic number 65. Atomic weight 158.925.
Dec 03, 2022

Erbium

A rare earth element of the lanthanide series associated with several other rare elements in the mineral gadolinite from Ytterby in Sweden. Symbol Er. It has atomic number 68 and an atomic weight of 167.26. The pure element is metallic with a bright, silvery luster. It is relatively stable in air, not oxidizing as quickly as some other rare earths. Its salts are rose-colored and give characteristic spectra, and the pink oxide has been added as a colorant in glass and porcelain enamel glazes. Its sesquioxide Er2O3 is called erbia.

Terbium

A metallic element of the rare earth group; used in lasers; occurs in apatite and monazite and xenotime and ytterbite
Dec 03, 2022

Erbium

A trivalent metallic element of the rare earth group; occurs with yttrium
