Talk:Borazon

Notes[edit]

How can it be employed in diamond laceration and yet, not be harder than a diamond? That's pretty confusing to me, Especially considering that it's more expensive to manufacture than diamonds. Wouldn't it be better instead diamonds be lacerated with other diamonds? I better stop writing now 'cause my head is spinning. --cave

I have absolutely no idea what I am talking about so take this with a huge grain of salt (or Borazon if you prefer). Own experience tells me that you can affect an object with another object, even if the latter is softer than the object being modified. More so if both materials are fairly close to one another in terms of hardness. It's just that the softer material will wear out fairly quickly. Maybe diamond would be more useful to modify other diamonds, but Borazon is preferred for other reasons such as price or other material qualities. --Moritz 11:51, 30 August 2005 (UTC)[reply]

That would explain it, altough I've read that Borazon is more expensive to manufacture than industrial-grade diamonds, even tough I can't confirm the veracity of this information. --cave 03:22, 1 September 2005 (UTC)[reply]

Far as I know, for the cutting and polishing of diamond, you would not want to use borazon as an abrasive, because it would score the face of the diamond... I believe (though the article on Diamond does not mention) that for polishing, a soft wheel and a slurry of fine abrasive is used. Martin Rudat(T|@|C) 07:23, 28 September 2005 (UTC)[reply]

How is the sentence "Borazon is the only substance that can scratch a diamond." affected by new materials such as aggregated carbon nanorods? --Ellisonch 04:56, 15 November 2005 (UTC)[reply]

Tradename[edit]

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)[reply]

facts incorrect, see ultrahard fullerite

Which one is harder?[edit]

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.

Abrasion[edit]

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)[reply]

Joke[edit]

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)[reply]
