Details
Yttrium is a silvery-metallic dark grey lustrous metal that is relatively stable in air. Finely divided yttrium metal is very unstable in air and turnings of the metal will ignite at temperatures above 400 °C. The metal is soft and ductile. It has a hexagonal close-packed structure, a density of 4.478 gm/cm3, a melting point of 1522 °C, and a boiling point of 3338 °C. Yttrium oxide, or yttria, occurs as a sesquioxide with the formula Y2O3. The oxide is a white powder with a specific gravity of 5.0 gm/cm3 and a formula weight of 225.81. Yttrium is most widely used in phosphors for white and grey colours in LEDs, and in tri-chromatic fluorescent lighting.For its physical and chemical properties, Yttrium is regularly alloyed with chromium, molybdenum, zirconium, titanium, aluminum and magnesium. Yttrium is used as a deoxidizer for vanadium and other nonferrous metals, and as a catalyst in the polymerization of ethylene. It has medical applications in cancer treatment, arthritis and joint inflammation, in artificial joints, prosthetic devices, and needles. The element can also be found in optical and camera lenses, cubic zirconia jewelry, super conductor materials, high performance spark plugs, yttrium-stabilized zirconia, solid electrolytes, exhaust systems,catalytic converters, turbocharger components, and piston rings. Purity: Y/TREM ≥ 99% - 99.99% min Packing: In iron drums with inner double PVC bags of 100kg net each, or packed according to customers' specifications.
