Abstract
Samples of lining and insulation from a transverse cross-section of an aluminum smelting cell were examined by X-ray diffraction and differential thermal analysis. Potlining was penetrated by catholyte, with its composition changing to correspond with the isotherm passing through each point. Penetration was limited by the eutectic temperature. Air leakage into the cell caused Na{in2}CO{in3} and CaO formation near the sides.
