Cubic BC[sub 2]N was synthesized from graphite-like BC[sub 2]N at pressures above 18 GPa and temperatures higher than 2200 K. The lattice parameter of c-BC[sub 2]N at ambient conditions is 3.642(2) Å, which is larger by 1.48% than would be expected based on ideal mixing between diamond and cubic boron nitride. The bulk modulus of c-BC[sub 2]N is 282 GPa which is one of the highest bulk moduli known for any solid, and is exceeded only by the bulk moduli of diamond and c-BN. The hardness of c-BC[sub 2]N is higher than that of c-BN single crystals which indicates that the synthesized phase is only slightly less hard than diamond. © 2001 American Institute of Physics.
