What is the use of the Ellingham diagram in metallurgy?
Show Hint
Ellingham diagrams are crucial in pyrometallurgy to compare the reducibility of different metal oxides and to select appropriate reducing agents based on temperature.
Updated On: Jun 20, 2025
- To calculate the boiling point of different metals.
- To predict the solubility of gases in metals.
- To determine the temperature at which a metal oxide can be reduced.
- To visualize phase changes in metal alloys.

The Correct Option is C
Solution and Explanation
The Ellingham diagram is a plot of Gibbs free energy change (\(\Delta G\)) versus temperature for various oxidation reactions.
In metallurgy, this diagram is used to determine the feasibility of reducing metal oxides to their respective metals at different temperatures.
The position and slope of the lines in the Ellingham diagram help in comparing the stability of different metal oxides and identifying the temperature above which a metal oxide can be reduced using a particular reducing agent such as carbon or carbon monoxide.
Thus, the primary use of the Ellingham diagram is to determine the temperature at which a metal oxide can be reduced effectively.
