Packing: | 0.1KGs, 0.2KGs, 0.5KGs Vacuum Bag or packing as per request. |
Storare: | Storing in sealed, dry and cool condition, not exposing to air for long time, avoiding moisture. |
Characteristics: | Black powder is extremely susceptible to oxidation and ignition 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. |
Packing: | 50KGs Iron Drum or 1000KGs Jumb Bag or packing as per request. |
Storare: | Storing in sealed, dry and cool condition, not exposing to air for long time, avoiding moisture. |
Characteristics: | Pink powder, slightly soluble in inorganic acid, insoluble in water. |
