Thermodynamic equilibrium predictions of Al/CuO, Al/Ag2O and Al/Fe2O3 thermitesa.
| Thermite reaction | Adiabatic temperature (°C) | Gas production (mmol g−1) | Major gas species |
|---|---|---|---|
| 2Al + 3CuO → Al2O3 (l) + 3Cu (l, g) | 2570 | 5.4 | Cu |
| 2Al + 3Ag2O → Al2O3 (l) + 6Ag (l, g) | 2163 | 4.3 | Ag |
| 2Al + Fe2O3 → Al2O3 (l) + 2Fe (l, g) | 2862 | 1.4 | Fe |
Assumptions: constant enthalpy and pressure with phase changes; without taking account of the oxide shell of aluminum. Data is taken from Fisher and Grubelich.50
