| Abstract: | The relation between thermodynamic stability of a metal oxide and standard free energy change for the reaction in which a metal oxide is formed from the elements in their stable forms is discussed,the thermodynamic meanings of the reduction of a metal oxide to the metal is interpreted,the thermodynamic bases for selecting reducing agent of different metal oxides are expounded. |
| Keywords: | metal reduction standard free energy change Ellingham diagram |
