| 41. | Yttrium oxide is also used to make yttrium iron garnets, which are very effective microwave filters.
|
| 42. | When quaternary ammonium salts are used as extractants, most yttrium will remain in the aqueous phase.
|
| 43. | Its spectrum also shows other s-process elements such as barium, yttrium, and lanthanum.
|
| 44. | When containing a substantial amount of oxygen, yttrium hydride is also found to exhibit photochromic properties.
|
| 45. | It's the root of four element names, Yttrium, Erbium, Ytterbium, and Terbium.
|
| 46. | Europium-doped yttrium vanadate was the first red phosphor to enable the development of color television screens.
|
| 47. | Yttrium has no known biological role, and exposure to yttrium compounds can cause lung disease in humans.
|
| 48. | Yttrium has no known biological role, and exposure to yttrium compounds can cause lung disease in humans.
|
| 49. | However, this model fails to address superconductivity in the homologue Pr123 ( praseodymium instead of yttrium ).
|
| 50. | Yttrium oxide is used as a common starting material for both materials science as well as inorganic compounds.
