WebEllingham diagram helps us to select a suitable reducing agent and appropriate temperature range for reduction. The reduction of a metal oxide to its metal can be considered as a competition between the element used for reduction and the metal to combine with oxygen. WebAn Ellingham diagram shows the relation between temperature and the stability of a compound. It is basically a graphical representation of Gibbs Energy Flow. In metallurgy, we make use of the Ellingham diagram to plot the reduction process equations.
WebEllingham diagrams plot the standard free energy of formation, \DeltaG fo, as a function of temperature. For a description of the uses, I recommend Free Energy of Formation of Binary Componds: An Atlas of Charts for … WebAn Ellingham diagram is a plot of 6G (change in Gibbs free energy) versus temperature, which, for our purposes, would be a temperature in a continuous furnace by zone or in a batch furnace by time in the cycle. The Ellingham diagram shown is …
