The massic energies of combustion in fluorine of two specimens of cubic boron nitride have been measured in a bomb calorimeter, the standard molar enthalpy of formation delta f 0 m H(c-BN, cr, 298.15 K) = -254.6š1.5 and the enthalpy of polymorphic transition delta trs m 0 H (298.15 K) = -3.5š1.5 of the process: h-BN (cr) -- c-BN (cr) have been determined. Those quantities are compared with the values determined previously.
