Terbium Metal Tb CAS 7440-27-9 For Magneto-optical Recording Material
Name: Terbium metal, distillation Terbium Molecular formula: Tb
CAS: 7440-27-9 Molecular weight: 158.93
Description: Terbium can be made into various forms: Terbium Foil, Terbium block, Terbium sheet, Terbium powder, Terbium sputtering target. Terbium and other rare earth elements coexist in monazite sand, and the content of terbium is generally 0.03%. Other sources are yttrium phosphate ore and black rare gold ore, both of which are oxide mixtures, containing up to 1% terbium, a small amount of which is found in the phosphorous cerium thorium sand and the silicon beryllium yttrium ore. Terbium is a soft and malleable silver gray rare earth metal. It is easy to be corroded by air at high temperature and very slow at room temperature. Soluble in acid, salt is colorless.

Package: Under Argon atmosphere or vacuum packaging, 25kg or 50kg per bag, also provide small package: 100g, 500g, 1kg, 5kg and other small packaging.
Use: The rotatory Glass Containing Terbium is the key material to manufacture rotator, isolator and circulator widely used in laser technology. Among the magneto-optical storage materials, the terbium magneto-optical materials have reached the scale of mass production. The storage capacity of the magneto-optical disk made of TB Fe amorphous film is increased by 10-15 times as a computer storage element.
