This program illustrates the derivation of equilibrium diagrams for oxidation of SiC with ozone. The main program OXID2D derives the equilibrium activity diagrams i.e., the equilibrium boundaries. The main program has 2 sub-routines (SubOXID_1 and SubOXID_2), which derive the standard free energy change of the oxidation reaction and equilibrium ozone pressures at temperatures below and above the melting point of SiO2. The sub-routine SubOXID_1 is for reactions in the lower temperature range (298.15-1900 K) where SiO2 is in the solid phase; the sub-routine SubOXID_2 is for reactions at temperatures above the melting point of SiO2 (2000-3200 K). The data from SubOXID_1 & 2 are imported into OXID2D and must be run prior to the main program.
