1980s
- In the early 1980s, Prof. Donald Sadoway’s MIT laboratory began research on an inert anode for aluminum manufacturing. In the late 1980s, he conceived of an electrolytic cell for the production of iron, and molten oxide electrolysis was born. Throughout the 1990s and 2000s, MOE research was extended to other metals before returning to electrolytic steelmaking and again focusing on inert anode technology
