Ellingham Diagram Oxides. Now here ellingham diagram comes in picture as it gives the information about the best suitable reducing agent for a specific metal oxide. The ellingham curve on the graph actually lies lower than most of the other metals such as iron.
Reed free energy of formation of binary compounds. Image will be updated soon for c co2 g 0 so reaction will be at equilibrium. The ellingham diagram originally constructed for oxides is a tool to find a variety of thermodynamic data quickly without the need for repetitive calculation.
These diagrams help us in predicting the feasibility of thermal reduction of an ore.
The diagram is essentially a graph representing the thermodynamic driving force for a particular reaction to occur across a range of temperatures. Image will be updated soon for c co2 g 0 so reaction will be at equilibrium. A general reaction expressing oxidation is given by. Rare earth oxides ellingham diagram xls author.
