The equilibrium potential of the cell Alup 1 NatiF, + A1808c,t, 1 Pt, 0, was determined from potential-decay curves to be 2.205 V at 1000Β°C. A Tafel plot of the anodic overvoltage. shows two straight portions with slopes RT/3F and RT/F, indicating a two-step discharge reaction of oxygen, with exchan
Titanium diboride is the most perspective material for protection of the cathode lining of aluminum electrolysis cells. One of the possible methods for obtaining a titanium diboride coating is an electrochemical synthesis from cryolite melt containing oxides of titanium and boron. In the present pap
