What Is Cubic Boron Nitride?

Cubic boron nitride (CBN) is a synthetic chemical compound made up of boron and nitrogen atoms in a one-to-one ratio. Unlike other types of boron nitride, it exists as a cubic crystal lattice, with its atoms arranged in a symmetrical, cube-shaped structure like the crystalline structure of diamond.

Boron nitride - WikiMili, The Best Wikipedia Reader

2020-11-23 · Structure of hexagonal boron nitride intercalated with potassium (B 4 N 4 K). Similar to graphite, various molecules, such as NH 3 [34] or alkali metals, [35] can be intercalated into hexagonal boron nitride, that is inserted between its layers. Both experiment and theory suggest the intercalation is much more difficult for BN than for graphite.
