Shock Synthesis of a Graphitic Boron‐Carbon‐Nitrogen System

Fine graphitelike boron‐carbon‐nitrogen particles were produced via vaporization and condensation of a powdered mixture of amorphous boron nitride/carbon black (a‐BN/CB) via shock compression. Electron microscopy showed that the particles were made of a graphitic layer sequence with a composition of (BN) 0.33 C 0.67 . The hexagonal lattice parameters of g‐(BN) 0.33 C 0.67 were a 0 = 0.2475 ± 0.0001 nm and c 0 = 0.676 ± 0.002 nm.
