In … WebNov 29, 2024 · The Ellingham diagram is used to determine the oxygen partial pressure being bubbled through the molten metal: Identify a point corresponding to a selected temperature on the line for: Fe + O → FeO, above M. Using this point, and the point O in the top left corner, draw a line across the diagram.
WebThe equilibrium partial pressure is found as follows: A line is drawn from the origin of the graph ( T = 0, Δ G = 0) through the point on the Ellingham line of interest, at the required temperature. The equilibrium partial pressure is read off at the point where the drawn line crosses the nomographic scale.
