Thermodynamic Modeling of the C90–N2 System

Using the method of computer thermodynamic modeling, the stability of higher fullerene C₉₀ heated in a nitrogen atmosphere at a pressure of 0.1 MPa is studied. The simulation is performed using the TERRA software package in the temperature range from 273 K to 3373 K. The equilibrium composition of compounds in the C₉₀–N₂ system is obtained and the physico-chemical processes causing the formation of these compounds are described. The equilibrium constants of the processes forming the equilibrium composition of compounds are calculated for different temperature ranges using the least squares method.
