Description

Determination of formation enthalpy of graphite-like boron nitride was conducted by the method of fluorine calorimetry for the purpose of testing reliability of developed methods of fluorination of dense BN modifications. BF3 compound was revealed in fluorination reaction products. Enthalpy of its formation was used to calculate formation enthalpy of graphite-like BN - ΔfH0=-250.6 ± 2.1 kJ/mol. Formation enthalpy of cubic (-16.2 ± 3.0 kJ/mol) and wurtzide-like (-12.6 ± 3.1 kJ/mol) modifications from graphite-like boron nitride was calculated according to thermochemical data. It was established that at 101.3 kPa in 0-1570 K range BN cubic modification was stable one. 10 refs
