Characteristic
Yttrium is a chemical element with the symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to the lanthanides and has often been classified as a "rare-earth element".
Phase at STP： solid
Melting point： 1799 K (1526 °C, 2779 °F)
Boiling point： 3203 K (2930 °C, 5306 °F)
Density (near r.t.)： 4.472 g/cm3
when liquid (at m.p.)： 4.24 g/cm3
Heat of fusion： 11.42 kJ/mol
Heat of vaporization： 363 kJ/mol
Molar heat capacity： 26.53 J/(mol·K)
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.
