Article changed over to new Wikipedia:WikiProject Elements format by maveric149. Elementbox converted 11:03, 14 July 2005 by Femto (previous revision was that of 09:59, 12 July 2005). 12 July 2005

Information Sources[edit]

Some of the text in this entry was rewritten from Los Alamos National Laboratory - Tantalum. Additional text was taken directly from USGS Tantalum Statistics and Information, from the Elements database 20001107 (via dict.org), Webster's Revised Unabridged Dictionary (1913) (via dict.org) and WordNet (r) 1.7 (via dict.org). Data for the table was obtained from the sources listed on the subject page and Wikipedia:WikiProject Elements but was reformatted and converted into SI units.

Capacitance[edit]

In case anyone wonders about my "capacitance" edit: it is not correct to say that tantalum has a higher capacitance than other substances (as the pre-edit version did). Capacitance is a property of an electronic component, not of a material; it would be like saying that titanium has a higher velocity than iron. (Sure, if you build a high-performance jet out of it, but...) I substituted what I think the author of that sentence probably meant, which is that tantalum's main electronic application is in capacitors with high capacitance.129.97.79.144 21:11, 2 Jun 2005 (UTC)

Absolutely makes sense even without an explanation. Femto 17:48, 3 Jun 2005 (UTC)

Abundance/rarity[edit]

Hello, The introduction to the article says "Tantalum is a rare metal, comprising just % of the universe, making it fifteen times less abundant in the universe than gold (which makes up %)". However, , not . It wasn't clear whether the abundance of tantalum, abundance of gold, or the "fifteen times less abundant" was incorrect. Can someone verify and edit this? — Preceding unsigned comment added by TheWurstPuns (talk • contribs) 14:29, 10 April 2015 (UTC)

Alloys[edit]

Nowhere in this article does it say ANYTHING about the most obvious relevant alloy of them all: tantalum-niobium. Similar alloys abound: zirconium-hafnium, scandium-yttrium, lanthanum-cerium, neodymium-praseodymium (didymium), uranium-plutonium, iridium-osmium, platinum-palladium, etc. In fact, when looking for pure elements, these alloys are often hard to get rid of.
Furthermore, this article says nothing about ion-exchange processes, which are often used to separate a) the lanthanide rare earths, b) the actinide rare-earths, and c) zirconium-hafnium.
In fact, ion-exchange is at the heart of the PUREX process = "plutonium-uranium extraction" process in nuclear engineering.24.156.78.205 (talk) 22:20, 1 June 2018 (UTC)
