Carbochlorination Reduction Process of Waelz ZnO: Characterization of Resulting ZnO-Based Oxides

Zinc-based oxides are the main products obtained after the Waelz process, a metallurgical method used industrially for the treatment of electric arc furnaces. These oxides have certain impurities in their composition, which can be a disadvantage. Carbochlorination reduction reactions have proven to...
