What does Ellingham Diagram mean?
Answers
★ An Ellingham diagram is a tool widely used in the field of extraction metallurgy in order to determine conditions such as the necessary temperature needed to reduce the ores of essential metals.
★ The diagram is a plot of Gibbs free energy versus temperature.
★ This form of energy reaction measures the required thermodynamic driving force to trigger a reaction.
★ A positive value means a reaction will not occur, while a negative value indicates otherwise.
★ This tool is very useful in various industries for monitoring and preventing corrosion.
Answer:
Hey dear ,
An Ellingham diagram is a graph showing the temperature dependence of the stability of compounds. This analysis is usually used to evaluate the ease of reduction of metal oxides and sulfides. These diagrams were first constructed by Harold Ellingham in 1944.
