Calculated heat of reaction of thermite reactionsa.
| Thermite reaction | Heat of reaction (cal g−1) |
|---|---|
| 2Al + 3Ag2O → 6Ag (l, g) + Al2O3 (l) | 504.8 |
| 2Al + 3CuO → 3Cu (l, g) + Al2O3 (l) | 974.1 |
| 2Al + Fe2O3 → 2Fe (l, g) + Al2O3 (l) | 945.4 |
| 4Al + 3AgFeO2 → 3Ag + 3Fe + 2Al2O3 (l) |
The thermodynamic data of AgFeO2 is unknown. Data is taken from Fischer and Grubelich50 without taking account of the oxide shell on aluminum.
