    Electrolyte: The electrolyte is a molten bath of cryolite (Na3AlF6) and dissolved alumina. Cryolite is a good solvent for alumina with low melting point, satisfactory viscosity, and low vapour pressure. Its density is also lower than that of liquid aluminium (2 vs 2.3 g/cm ), which allows natural separation of the product from the salt at the bottom of the cell. The cryolite ratio (NaF/AlF3) in pure cryolite is 3, with a melting temperature of 1010 °C, and it forms a eutectic with 11% alumina at 960 °C. In industrial cells t

    Suppliers Hit A Road BumpAnd Aluminium Producers StumbledFinal RemarksThe United States and China are two dominant suppliers of calcined pet coke to global smelters, and 75% of the global aluminium industry relies on Beijing’s CTP production. But China is starting to produce more steel from its growing domestic supply of scrap – partly by using the EAF (electric arc furnace) process, partly by using more scrap (and less coke) in the blast furnace and converter process. As a result, the Chinese CTP supSee more on aluminiuminsiderPublished: 2018-12-04

  • Aluminium for Future Generations – Anode Production

    Prebake anodes are produced in an area of the smelter called a “green mill” and are made from petroleum coke, pitch and recycled anode butts (the ends of the consumed anodes remaining at the end of their life) returned from the smelting process. These materials are mixed together in heated containers and poured into moulds. Once formed, the anodes are transferred to a “bakehouse”.
