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)

Wrong geochemical-mineralogical data

edit

"Most commonly encountered are oxides of Ta(V), which includes all minerals." Not true. Native tantalum has Ta(0), and Ta is also not pentavalent in tantalcarbide, TaC. And that's not all the exceptions.

Bad Map

edit
 
Map of world tantalum production in 2015.

Text around map says Rawanda, highlight isn’t. 2601:281:D57F:950:E5EB:A6C9:CA9D:472F (talk) 04:10, 4 August 2022 (UTC)Reply

  • Which map? The 2015 map has Rwanda highlighted in green. I do agree, however, that the color scheme chosen is very misleading, as it overemphasizes the minor producers over those with ~50% share. –LaundryPizza03 (d) 23:22, 4 August 2022 (UTC)Reply
