Dysprosium alloys

Silvery metal, that can be cut with a knife. Terbium alloys and additives are widely used in optoelectronics to burn CDs as well as in laser printers. The pronounced magnetostriction (Joule effect) makes "terfenol-D" (terbium-dysprosium-iron) indispensable in sonar technology. The physics of the element appears to be more interesting than its chemistry, in which it is rarely used in catalysis.

There are not many uses for dysprosium. Scientists continue to experiment with it as a possible alloy metal (it has a high melting point) to be mixed with steel to make control rods that absorb neutrons in nuclear reactors. There are only a few commercial uses for dysprosium, such as a laser material and as a fluorescence activator for the phosphors used to produce the colors in the older TV and computer cathode ray tubes (CRTs). When combined with steel or nickel as an alloy, it makes strong magnets.

Dysprosium is also used to make alloys for various electrical and electronic devices. An alloy is made by melting and mixing two or more metals. The mixture has properties different than any of the elements. Some dysprosium alloys have very good magnetic properties that make them useful in CD players. The element is also used in some hybrid cars.

Lai -j Ce TbyP04 exhibit strong green emission radiation. Such kinds of compounds are called phosphors and are used to display color in television. Terbium is also used as an alloy material in compact discs, see also Cerium Dysprosium Erbium Europium Gadolinium Holmium Lanthanum Lutetium Neodymium Praseodymium Promethium Samarium Ytterbium.
