    Interesting how the diamond sprays don’t have the crystalline form expected. Interesting, but not surprising, at how perfect the crystals are in the CrOx.

      Also, a common misconception is that cubic boron nitride (CBN) is comprised of cube-shaped particles.

      What I meant was: I’d find it interesting to see the alumina ceramic (sintered) stones.
