Thermodynamic calculation of the B-C system at pressures to 24 GPa

TL;DR

This study models the phase diagram of the boron-carbon system under pressures up to 24 GPa using thermodynamic methods informed by experimental data, revealing how phase relationships evolve at high pressures.

Contribution

It provides a thermodynamic model of the B-C system at high pressures, incorporating experimental data to predict phase diagram topology changes up to 24 GPa.

Findings

Phase diagram topology changes with pressure

Thermodynamic models align with experimental data

Predictions of high-pressure phase stability

Abstract

The evolution of topology of the B-C phase diagram has been studied at pressures up to 24 GPa using models of phenomenological thermodynamics with interaction parameters derived from experimental data on phase equilibria at high pressures and high temperatures.
