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. Axiosaurus 07:30, 2 May 2007 (UTC)

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)
