Yttrium (Y) Disc

Product Information

Yttrium is a highly crystalline iron-gray, rare-earth metal. Yttrium is fairly stable in air, because it is proteced by the formation by the formation of a stable oxide film on its surface, but oxidizes readily when heated. It reacts with water decomposing it to release hydrogen gas, and it reacts with mineral acids. Shavings or turnings of the metal can ignite in air when they exceed 400 °C. When yttrium is finely divided it is very unstable in air. In metallurgy, small additions of yttrium are used for grain refinement, for example in iron-chromium-aluminium heating wire alloys, chromium, molybdenum, titanium and zirconium alloys. It has a strength-increasing effect in aluminium and magnesium alloys.

ATT specializes in producing Yttrium as rolled discs in various thicknesses and sizes. Most discs are produced from cast ingots for use. ATT casts any of the rare earth metals and most other advanced materials into rod, bar or plate form, as well as other machined shapes and through other processes such as nanoparticles and in the form of solutions and organometallics. We also produce Yttrium as rods, powder and plates. Other shapes are available by request.

Yttrium (Y) Disc Application

The most important uses of yttrium are LEDs and phosphors, particularly the red phosphors in television set cathode ray tube displays. Yttrium is also used in the production of electrodes, electrolytes, electronic filters, lasers, superconductors, various medical applications, and tracing various materials to enhance their properties.

Reactivity Profile

Yttrium in bulk is stable in air due to the formation of oxide films. Powder or dust is light-sensitive and air-sensitive and flammable in the air and (Hazardous Chemicals Desk Reference, p. 861(1987)). Reacts with water to form gaseous hydrogen (H2). Reacts with strong oxidizing agents, strong acids, strong bases, and halogens. The products of these reactions are irritating and toxic.

Packing of Yttrium (Y) Disc

Standard Packing:

Typical bulk packaging includes palletized plastic 5 gallon/25 kg. pails, fiber and steel drums to 1 ton super sacks in full container (FCL) or truck load (T/L) quantities. Research and sample quantities and hygroscopic, oxidizing or other air sensitive materials may be packaged under argon or vacuum. Solutions are packaged in polypropylene, plastic or glass jars up to palletized 440 gallon liquid totes Special package is available on request.

ATTs’Yttrium (Y) Disc is carefully handled to minimize damage during storage and transportation and to preserve the quality of our products in their original condition.
