electrical properties

Unless Ultrahard fullerite is electrically conducting, it should be noted that BC is the hardest known electrically conducting material. --Dschwen 07:19, 12 Jan 2005 (UTC)

Better if we give its electrical conductivity or resistivity (since it's not a binary property). - Rod57 (talk) 16:28, 25 October 2021 (UTC)

Printing error?

In this article the boiling point is stated to be >3 500 °C. Several other sources state >2 500 °C. No other reference to 3 500°C has been found, so I suspect English WP to be in error. I suggest investigation and amendment if printing error is verified. / 82.182.149.179 18:35, 30 August 2007 (UTC)

I trust that you did a thorough research, and editted the boiling point. Anyway, if it is above 3500 C, it is above 2500 C too, isn't it? Preslav (talk) 07:51, 5 March 2009 (UTC)

Done, I happened to have a piece lying about. Preslav (talk) 07:51, 5 March 2009 (UTC)

pKa?

How could there be a pKa for a perfectly covalent compound (which is also insoluble in water)? I think there's something odd... — Preceding unsigned comment added by 151.65.169.97 (talk) 14:08, 14 November 2012 (UTC)

Reference 2 leads to 404 page

The external article cited in reference 2 is linked to http://www.app.com/article/20120811/NJNEWS/308110051/Rutgers-working-on-body-armor, but that link seems to lead to a possibly-irrelevant website ("app.com") and a 404 page.

Reference 2:

"Rutgers working on body armor". Asbury Park Press. Asbury Park, N.J. August 11, 2012. Retrieved 2012-08-12. ... boron carbide is the third-hardest material on earth.

Add bulk modulus and electrical resistivity

Add bulk modulus (in GPa) and electrical resistivity please. - Rod57 (talk) 16:25, 25 October 2021 (UTC)

hopping-type transport

Section Semiconductor properties has "Boron carbide is a semiconductor, with electronic properties dominated by hopping-type transport". I put "hopping-type transport" into the Search Wikipedia box, and the only hit was this article. I think it ought to be explained, either here or in a separate article.

Nuclear Applications section cuts off mid-sentence

The closing sentence of the 'Nuclear Applications' section is incomplete: "Nuclear applications of boron carbide include shielding, ". Followed by a ill-formed reference "name=w330>Weimer, p. 330</ref>". Schneckenberg (talk) 08:39, 19 April 2022 (UTC)
