| Storare: | Storing in sealed, dry and cool condition, not exposing to air for long time, avoiding moisture. |
| Characteristics: | Black metal powder, easily oxidized in the air. |
| Application: | 1. It is a very valuable material in nuclear reactor control rods because it can absorb more neutrons than any other element. |
| 2. It is a dopant in certain types of glass in lasers and other optoelectronic devices; it is also used to make fluorescent glass. | |
| 3. Can be used in quantum memory chips, which can reliably store information for several days at a time. These can store sensitive quantum data in hard disk-like devices and ship them nationwide. |
