Uses of Niobium Niobium is used with iron and other elements in stainless steel alloys and also in alloys with a variety of nonferrous metals, such as zirconium, Niobium alloys are strong and are often used in pipeline construction The metal is used in superalloys for jet engines and heat resistant equipment Niobium is also used for jewelry
A list of all the elements accepted by IUPAC Set is organized by the element name as the term, and the location on the PT as the "definition" Have fun!
In addition, production of many mineral commodities has become concentrated in relatively few countries (for example, tungsten, rare-earth elements, and antimony in China; niobium in Brazil; and platinum-group elements in South Africa and Russia), thus increasing the risk for supply disruption owing to political, social, or other factors

The mode of occurrence of the gold and platinum group metals is compatible with the syngenetic hypothesis As such, this would imply that the Olivine Rhyolite member of the Moonstone Formation to be a very attractive exploration target for gold, palladium and platinum
Group 5 (by IUPAC style) is a group of elements in the periodic table Group 5 contains vanadium (V), niobium (Nb), tantalum (Ta) and dubnium (Db) This group lies in the d-block of the periodic table The group itself has not acquired a trivial name; it belongs to the broader grouping of the transition metals
platinum clad niobium anodes in deep groundbeds The anode consists of a solid niobium rod 12 mm diameter and clad with 001 mm of platinum Again, the length of the anode depends on the required current output and they have been constructed in lengths ,
