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. Applications: Valency three europium produces a red radiance and valency two europium produces a blue radiance. When both valences are combined a white light is produced which is used in compact fluorescent bulbs. Molecular Formula: EuH2 Alfa Chemistry Materials product group: Metal Manufacturer data sheet |
