Talk:Calcium hexaboride

Misleading claim of high electrical conductivity
The introductory paragraph says that calcium hexaboride has high electrical conductivity, yet the numbers I can find represent low conductivity relative to metals or to lanthanum hexaboride, a similar material. Many webpages repeat the conductivity claim from here. I think the description is misleading, and it should at least qualify what "high" is relative to. Published conductivity numbers vary a lot, so I couldn't decide what it should say.

Some resistivity numbers I found:


 * 10^10 ohm-meters, stated in the second section of the article.
 * 10^-6 ohm-meters [], table on first page.
 * 10^-3 ohm-meters to 10^-2 ohm-meters [], table 1.
 * 2*10^-4 ohm-meters [], figure 1. Note the explanation of the figure's scale.

Values around 10^-3 would mean the resistivity is like amorphous carbon, which has low conductivity for a conductor. Amorphous carbon is used in resistors because of its low conductivity. — Preceding unsigned comment added by 104.55.37.220 (talk) 21:55, 30 April 2023 (UTC)

The picture is at odds with the rest of the article as it shows Cs octahedrally coordinated by B! The CsCl like structure is made up of B6 units and Ca in place of the Cs and Cl ions.

The text prior to 1 June 2009 was stuffed with (self-promotion ?) links to journal articles on CaB6 having extremely little or no any relation to the text. Beware ! Materialscientist (talk) 09:52, 1 June 2009 (UTC)
