Using in situ high-pressure synchrotron X-ray diffraction and diamond anvil cell (DAC) techniques, the phase transition and physical characteristics of B0.47C0.23N0.30 compound were observed in the pressure range of 1.4~30 GPa. The experimental results showed that the B-C-N compound experiences a phase transition from hexagonal structure to wurtzite phase at 14.9 GPa. The pressure dependences of the lattice parameters and volume of wurtzite-type B-C-N were calculated. By fitting the Brich-Murnaghan equation of state to the pressure-volume data, the bulk modulus of wurtzite-type B-C-N compound was obtained as (275±26) GPa, which is very close to the value of (282±15) GPa for the cubic BC2N.
