|
| An optical material characterized by comprising a strontium barium niobate single crystal containing europium and cerium as impurities. |
|
| For example, the mare basalts were depleted in aluminum and europium, whereas the anorthosites were loaded with aluminum and enriched in europium. |
|
| Very little information exists on the use and safety of europium chloride. |
|
| Other minor applications include the use of europium in X-ray screens, in nuclear reactor control rods as neutron absorbers, in super-conducting alloys, and as a material in the manufacture of lasers. |
