You got me, Vag. I did a simple search and got this:

Whatever it is, it's the compound they make Billy Mays' beard from.

Wurtzite boron nitride is only 18% harder than diamond
Both are extremely rare

Re: What the HECK is londaleite ???
I hear ya' Vag. One of the stones I use is technically 400 grit, but it is marked borride. Gee, I wish I hadn't slept in chemistry class.Vagrant wrote:Both are extremely rare
Even with stones and various grit sizes, I feel the same as I do with Rc hardness ratings. You reach a certain point, and then after that it's just braggin' rights.
But my question is, what do they use londaleite for, anyway?

So far they don;t have enough to use it
But, IF they can syntesize it they will use it as a possible replacement for dianond on some cutting tools or abrasives

Vagrant, your starting to scare me.
We have compounds that don't exist scheduled for our drills. We have anti-matter under the vatican. We have a Yamaha with 200 horsepower. Kendra is pregnant.
It's moving too fast, I tell ya, it's just moving too fast...!
