(Fred) Publication date Topics Niobium, Tantalum Publisher Amsterdam, New York [etc.] Elsevier Pub. : Abstract. Niobium and tantalum are rare refractory metals of large industrial value. Their reserves belong to “critical” raw materials, which leads to the necessity of evaluating the risks associated with the presence of primary and technogeneous raw-material sources of niobium and tantalum and with the influence of these factors on the offer and demand for these metals.

Niobium and Tantalum. The early histories of these elements are so intertwined that it is hardly worthwhile to consider them separately. Their common history begins on Novemwhen Ch. Hatchett made a report to a session of the Royal Society about the discovery of a.

History. Tantalum was discovered in Sweden in by Anders Ekeberg, in two mineral samples – one from Sweden and the other from Finland. One year earlier, Charles Hatchett had discovered columbium (now niobium), and in the English chemist William Hyde Wollaston compared its oxide, columbite with a density of g/cm 3, to that of tantalum, tantalite with Pronunciation: /ˈtæntələm/ ​(TAN-təl-əm).

Niobium and columbium are synonymous names for the chemical element with atomic number 41; columbium was the name given inand niobium (Nb) was the name officially designated by the International Union of Pure and Applied Chemistry in Niobium in the form of ferroniobium is used worldwide, mostly as an alloying element in steels and in superalloys.

A classic paper is Dick Schrock's review of the chemistry of niobium and tantalum alkylidene complexes - compounds with a double bond between the metal and carbon. This paper contains a picture of one of my favourite organometallic compounds - actually a tantalum compound - in which the metal is sandwiched between two organic rings and.

Columbium and niobium were shown to be the same element. The names columbium and niobium were both used to identify this element for almost another century, with columbium being preferred in the Americas.

It was not until that the International Union of Pure and Applied Chemistry (IUPAC) officially adopted niobium as the name for this element.

A systematic review of the oxide minerals of niobium and tantalum is presented, including varietal names, crystal chemistry, structural features, relationships to other phases and paragenesis of.Niobium is widely distributed in nature; it is about one and a half times as abundant as lead.

It occurs in the minerals columbite and tantalite, together with tantalum. Separating niobium and tantalum is difficult. The element was discovered in by Charles Hatchett and first isolated in by C. W. Blomstrand. Transition-metal dichalcogenides (TMDs) are at the forefront of research for their promising catalytic abilities and unique materials properties.

With great interest in the study of mono- or few-layered TMDs, we seek to fundamentally explore the effects of doping on bulk TMDs, particularly MoS2 and WS2 for the hydrogen evolution reaction (HER) and oxygen .
