cryolite-alumina electrolyte with cryolite ratio of 2.7 was carried out at an initial temperature of 970 &deg;C and the anode current density of 0.5 A/cm<sup>2</sup> in a 15A lab-scale cell in order to study the formation of the side ledge during electrolysis and the alumina distribution between electrolyte and side ledge. The alumina contained 35.97% &alpha;-phase and 64.03% &gamma;-phase with the particles size in the range of 10-120 &mu;m. The cryolite ratio and the alumina concentration were determined in molten electrolyte during electrolysis and in frozen bath after electrolysis. The side ledge in the electrolysis cell was formed only by the 13<sup>th</sup> hour of electrolysis. With a slight temperature decrease a significant increase in the side ledge thickness was observed. The basic components of the side ledge obtained by the XRD phase analysis were Na<sub>3</sub>AlF<sub>6</sub>, Na<sub>5</sub>Al<sub>3</sub>F<sub>14</sub>, Al<sub>2</sub>O<sub>3</sub>, and NaF<sup>.</sup>5CaF<sub>2</sub><sup>.</sup>AlF<sub>3</sub>. As in the industrial cell, the increased alumina concentration in the side ledge formed on the cell walls and at the ledge-electrolyte-aluminum three-phase boundary during aluminum electrolysis in the lab cell was found (FTP No 05.604.21.0239, IN RFMEFI60419X0239).</p> <iframe src="https://publications.waset.org/10010975.pdf" style="width:100%; height:400px;" frameborder="0"></iframe> <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/search?q=Alumina" title="Alumina">Alumina</a>, <a href="https://publications.waset.org/search?q=alumina%20distribution" title=" alumina distribution"> alumina distribution</a>, <a href="https://publications.waset.org/search?q=aluminum%20electrolyzer" title=" aluminum electrolyzer"> aluminum electrolyzer</a>, <a href="https://publications.waset.org/search?q=cryolite-alumina%20electrolyte" title=" cryolite-alumina electrolyte"> cryolite-alumina electrolyte</a>, <a href="https://publications.waset.org/search?q=side%20ledge." title=" side ledge.
