Using Brillouin scattering the three independent elastic stiffness constants [ital c][sub [ital ij]] of single-crystal cubic boron nitride have been measured: [ital c][sub 11]=820, [ital c][sub 12]=190, and [ital c][sub 44]=480 GPa. The resulting bulk modulus, 400 GPa, is in reasonable agreement with two independent determinations obtained from x-ray measurements in a diamond anvil cell. Using the bulk modulus it is found that the x-ray results are best fitted with a value of [ital dB]/[ital dP]=3.0.
