Europium Dihydride Quick inquiry Where to buy Suppliers range | Europium react with hydrogen at pressures lower than 1 atm and at elevated temperatures to form dihydride with an orthorhombic structure [1,2]. It is ferromagnetic at 25 K (-248 °C, or -415 °F) and does not react further under pressures up to 400 atm at 400 °C. Uses: Valency three europium produces a red radiance and valency two europium produces a blue radiance. When both valencies are combined a white light is produced which is used in compact fluorescent bulbs. Group: Eu. CAS No. 70446-10-5. Molecular Weight: 154g/mol. Molecular Formula: EuH2. | |
Europium (III) Hydride Quick inquiry Where to buy Suppliers range | The Europium metals readily react with hydrogen to form EuH2, and, by raising the hydrogen pressure, the trivalent Eu metals also form the EuH3 phase. Both the EuH2 and EuH3 phases are nonstoichiometric (that is, the numbers of atoms of the elements present cannot be expressed as a ratio of small whole numbers). Uses: Valency three europium produces a red radiance and valency two europium produces a blue radiance. When both valencies are combined a white light is produced which is used in compact fluorescent bulbs. Group: Eu. CAS No. 70446-10-5. Molecular Weight: 155g/mol. Molecular Formula: EuH3. |
