|
| 8. | Hatchett had named the new element " columbium ", from the ore in which niobium and tantalium coexist.
|
| 9. | There are also deposits of lithium ( world's third largest reserve ), beryllium, and columbium.
|
| 10. | The steels are alloys, with titanium, columbium and vanadium each used in ratios of a few parts per thousand.
