THERMODYNAMIC PROPERTIES OF ROCK-FORMING OXIDES, α-Al2O3, Cr2O3, α-Fe2O3, AND Fe3O4 AT HIGH TEMPERATURES AND PRESSURES

THERMODYNAMIC PROPERTIES OF ROCK-FORMING OXIDES, α-Al2O3, Cr2O3, α-Fe2O3, AND Fe3O4 AT HIGH TEMPERATURES AND PRESSURES

Equations of state of corundum (α-Al2O3), eskolaite (Cr2O3), hematite (α-Fe2O3), and magnetite (Fe3O4) are constructed based on the Helmholtz free energy by simultaneous optimization of ultrasonic, X-ray diffraction, dilatometric, and thermochemical measurements. The magnetic contribution to Cr2O3,...
