Product Description

The properties of the anode are largely set during the baking process and must be carefully controlled to ensure an acceptable output efficiency and reduce the amount of undesirable byproduct produced.^[3] To that end, the aluminium smelting industry has settled on a range of acceptable values for commercial mass-produced anodes for the purpose of consistent, optimal performance.
