Description
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 formationΔfH0m (c-BN, Cr, 298.15 K) = -254.6±1.5 and the enthalpy of polymorphic transition ΔtrsH0m (298.15 K) -3.5±1,5 of the process:h-BN (cr) → c-BN (cr) have been determined. Those quantities are compared with the values determined previously. (author)
