The article studies the dependence of stability of lining materials aluminum electrolysis cells on composition of the electrolyte and mechanical activation of powder grog. “The bowl method” was used to compare the reaction of a traditional fire clay in a contact with sodium and “Lithium” electrolytes at 10000 С. The research brings to the light the effect of electrolytes on fireclay, mechanically activated for different times. XRF revealed chemical composition of products of interaction between chamotte and electrolytes. The article shows that the destruction of refractory bricks under the effect of lithium electrolyte (1%) more intensive than the sodium electrolyte. Chamotte behavior explained by the phase formation at the melt-lining. The chemical reactions of interaction were proposed. The research found that the mechanochemical activation chamotte powder reduces the penetration of the molten electrolyte into the refractory lining, which increases kriolitoustoychivosti and prolong the life of the cathode.
