tantalum-niobium ore

Tantalum-niobium is a general term for minerals containing tantalum and niobium. There are more than a hundred types. Among them can be used as ore mining, mainly by tantalite, niobium iron ore and pyrochlore. Tantalum (Ta) niobium (Nb) belongs to the high melting point (tantalum 2996 ° C, niobium 2468 ° C), high boiling point (tantalum 5427 ° C, niobium 5127 ° C) of rare metals, the appearance of steel, grayish-white luster, the powder was dark gray, with gas absorption, corrosion resistance, superconductivity, unipolar electrical conductivity and at high temperatures in the intensity of high characteristics. It is used for the preparation of tantalum oxide and niobium oxide, and the refining of tantalum and niobium. The grade analysis can be quickly analyzed by the special Tantalum-Niobium Wave Ore Analyzer.
