Thermodynamic Calculation of the Al–B–N Phase Diagram at Pressures up to 9 GPa

The aluminum–boron–nitrogen phase diagram is calculated at a pressure from 0.1 MPa to 9 GPa by the models of phenomenological thermodynamics in the Thermo-Calc software package with interaction parameters from literature data and equation of states for competing phases. The comparison of our calcula...

Description
Summary:	The aluminum–boron–nitrogen phase diagram is calculated at a pressure from 0.1 MPa to 9 GPa by the models of phenomenological thermodynamics in the Thermo-Calc software package with interaction parameters from literature data and equation of states for competing phases. The comparison of our calculation results with the experimental studies of the phase composition of polycrystalline boron nitride samples sintered ay high pressures and temperatures shows their agreement.
