Yttrium (Y) Metal and Compouds

Yttrium is a highly crystalline iron-gray, rare-earth metal. Yttrium is quite stable in air, that’s because it is protected 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. Turnings or shavings of the metal will ignite in the air when they exceed 400 °C. When finely divided yttrium is very unstable in air.

Yttrium Applications

The element is usually used as oxide yttria, Y2O3, which is employed in making red phosphors for color television picture tubes. Yttrium metal has found some use alloyed in small amounts with other metals and it's wont to increase the strength of aluminum and magnesium alloys. When added to forged iron it makes the metal more workable. Although metals are generally excellent at conducting heat, there's an alloy of yttrium with chromium and aluminum which is heat resistant. Yttrium oxide is packaged in glass to make it heat- and shock-resistant, and is employed for camera lenses. Yttrium oxide is suitable for creating superconductors, which are metal oxides that conduct electricity with no loss of energy.
