1. The hull would have consisted of columbium and nickel alloy. 2. :It's the primary ore of " columbium ", now called niobium. 3. In 1809, the English chemist William Hyde Wollaston wrongly concluded that tantalum and columbium were identical. 4. The English chemist Charles Hatchett reported a new element similar to tantalum in 1801 and named it columbium . 5. The English chemistCharles Hatchett reported a new element similar to tantalum in 1801, and named it columbium . 6. The " columbium " discovered by Hatchett was probably a mixture of the new element with tantalum. 7. Subsequently, there was considerable confusion over the difference between columbium ( niobium ) and the closely related tantalum. 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.
