Europium is a rare-earth metal from the lanthanide group. It is a soft heavy metal with high technical importance for the production of phosphors. The element is paramagnetic, but at very low temperatures it shows antiferromagnetism. In dry air, the metal oxidizes quickly. In humid air, it becomes covered with a yellow hydroxide layer. In water, it dissolves with the formation of hydrogen. In addition, europium reacts with most non-metals.
The europium price is always up to date in the Evek GmbH online shop. Our goal is your trust in us and your satisfaction with our service.
The main application area of europium is the production of phosphors. Here, it is used as a doping agent. In addition, the element is used for coating glass in mercury vapor lamps (high-pressure lamps). This makes the light white and more natural. Since europium is a good neutron absorber, it is also used as a neutron absorber in nuclear reactors.
Europium is used:
- as a doping agent for the production of phosphors;
- as a neutron absorber in nuclear reactors;
- in mercury high-pressure lamps;
- as a phosphor.
Europium is characterized by:
- paramagnetism;
- antiferromagnetism at very, very low temperatures;
- solubility in water with hydrogen formation;
- phosphorescence;
- reaction with most non-metals;
- oxidation in dry air.
