| Assay | 99.9% trace metals basis |
| Particle size | -80 mesh |
| Application | Skutterudites such as Cobalt antimonides are widely studied as a promising thermoelectric (TE) material for high-temperature applications. The thermoelectric power of the cobalt antimonides can be further improved by suitable doping or by filling the interstitial voids with guest atoms and also by nanostructuring.In recent years CoSb is also used as electrode material for lithium ion batteries. |
