best known for his Ellingham diagrams. Ellingham diagram summarizes a large amount of information aboutEllingham diagrams are a particular graphical form of the principle that the thermodynamic feasibility of a reaction depends on the sign of ΔG so therefore carbon can be used to reduce it (note: reduction can also mean to remove the oxygen from a compound). This is done in a blast furnace. The most common ore of iron is called haematite (iron(iii) oxide). Its formula is Fe 2 O 3.2a. Extraction of Iron in a blast furnace. Sadly
