- Ilmenium was the proposed name for a new element found by the chemist R. Hermann in 1847. During the analysis of the mineral samarskite, he concluded that it does contain an element similar to niobium and tantalum. The similar reactivity of niobium and tantalum complicated preparation of pure samples of the metals and therefore several new elements were proposed, which were later found to be mixtures of niobium and tantalum. The differences between tantalum and niobium, and the fact that no other similar element was present, were unequivocally demonstrated in 1864 by Christian Wilhelm Blomstrand, and Henri Etienne Sainte-Claire Deville, as well as Louis J. Troost, who determined the formulas of some of the compounds in 1865 and finally by the Swiss chemist Jean Charles Galissard de Marignac Although it had been proven that ilmenium is only a mixture of niobium and tantalum, Hermann continued publishing articles on ilmenium for several years. The name "ilmenium" is a reference to the Ilmensky Mountains. (en)
- Ilmenium是歷史上一度以為是化學元素的物質。早於1846年，有人聲稱發現了新元素，原子序為43，43號元素。一年後，也就是1847年時，化學家R.赫爾曼將1846年有人聲稱發現的43號元素命名為Ilmenium，他分析了發現那個元素的所得到的結論是，它確實包含與鈮和鉭相似的元素。它有類似鈮和鉭的複雜製備反應性，因為性質與鈮和鉭不太相同，因此以為是新元素，但後來發現它只是鈮和鉭的混合物。 1864年，Christian Wilhelm Blomstrand明確地表明，這些並非可以證明Ilmenium存在的事實，之後的幾年Ilmenium被與Pelopium相同的證明過程發現它只是鈮和鉭的混合物。雖然已經證明ilmenium是鈮和鉭的混合物，但赫爾曼還是繼續發表ilmenium的論文與相關文章好幾年。 (zh)
