yttrium (nonferrous metal, <metal by composition or origin>, ... Materials (hierarchy name)) |
|
Note: Chemical element having symbol Y and atomic number 39. Yttrium resembles lanthanide metals very closely and is often classified as a ‘rare earth element.' Yttrium’s most important use is for making the phosphors used in television screen displays and in LEDs. Yttrium phosphors emit a clear red light when excited by electrons.

Additional Notes: |
|
| Dutch ..... Chemisch element met symbool Y en atoomnummer 39. Yttrium lijkt sterk op lanthanidemetalen en wordt vaak geclassificeerd als 'zeldzame aarde'. De belangrijkste toepassing van yttrium is de fabricage van fosforescerende stoffen voor televisieschermen en leds. Fosforescerende stoffen met yttrium stralen helder rood licht uit wanneer ze worden aangeslagen door elektronen. |
