Terbium Oxalate is highly insoluble in water and converts to the oxide when heated (calcined). Terbium Oxalate is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered. Terbium is primarily used in phosphors, particularly in fluorescent lamps and as the high intensity green emitter used in projection televisions. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Terbium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f96s2. In its elemental form terbium's CAS number is 7440-27-9. The terbium atom has a radius of 176.3.pm and it's Van der Waals radius is unknown. Terbium is primarily used in phosphors, particularly in fluorescent lamps and as the high intensity green emitter used in projection televisions, such as the yttrium-aluminum-garnet (Tb:YAG) variety. Terbium is available as metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high purity); metals in the form of foil, sputtering target, and rod, and compounds as submicron and nanopowder. Terbium responds efficiently in x-ray excitation and is, therefore, used as an x-ray phosphor. Terbium alloys are also used in magneto-optic recording films, such as Tb-Fe-Co. Terbium was first discovered by Carl Mosander in 1843.
