Talk:Borazon

Tradename
Is Borazon a trade name or a common name for Cubic Boron Nitride? and if so, should this article be merged with Boron nitride? --Martin Rudat(T|@|C) 04:48, 26 March 2006 (UTC)

facts incorrect, see ultrahard fullerite

Which one is harder?
Third hardest does not compute together with the text about diamonds which says "Diamond is the hardest known natural material (third-hardest known material below aggregated diamond nanorods and ultrahard fullerite)". Shouldn't that make ultrahard fullerite harder than Borazon and therefor make Borazon the fourth hardest substance since ultrahard fullerite wasn't natural either? Which one is harder? —Preceding unsigned comment added by 213.112.198.5 (talk • contribs)

Answer: Borazon is the third-hardest man-made substance according to the article. It may be correct, however, to state Borazon is the fourth- hardest known substance overall. —Preceding unsigned comment added by 76.17.105.123 (talk • contribs)

Abrasion
The overal picture is more complex though. If I read this article correctly Borazon is less brittle than diamonds. Traditionally a diamond was used to cut another diamond but more modern practice is to use a laser

Where a hardened shaft was running in softer bearing, minute particles from the harder shaft would become embedded in the softer bearing and gradually abrade the harder shaft.AT Kunene (talk) 10:24, 4 October 2012 (UTC)

Joke
There used to be a joke about the discoverer of Borazon as "being the only man to scratch a girls best friend". — Preceding unsigned comment added by AT Kunene (talk • contribs) 10:26, 4 October 2012 (UTC)
