The effect of chemical composition on the cationic conductivity of mixed alkali metals β"-polyferrites was established. Cationic conductivity is determined by the mobility of alkali metal ion in inter-unit space which in turn depends on the ratio of cation radius and width of inter-unit space. The conductivity increases with z, and at the same z in the range of 0.28 – 0.4 becomes constant (z in the formula Me2-zAdzFe11O17, where Me - the basic alkali metal, Ad - introduced alkali metal ion, which has the larger radius (Cs, Rb)) for all samples. This is due to the structural features of polyferrites.
Key words: (poly)ferrite, cation conductivity, solid electrolyte
