ResumoA number of alkali borate glasses containing tin oxide of base composition (100−X) % B2O3 + X % Me2O + Y SnO2 where Me = Li, Na or K, X = 10, 20 or 30 and Y is the quantity of SnO2 introduced, were prepared and studied by the Mössbauer effect. It was shown that the value of the isomer shift increases while the value of the quadrupole splitting decreases with increasing ionic radius of the alkali ion. The value of the isomer shift and quadrupole splitting decrease with increasing alkali content. The observed asymmetry in the absorption lines was attributed to the Goldanskii effect. An explanation is suggested for the dependence of the ratio of the various valence and coordination structural states of the tin in the glass on the amount and nature of the alkali ions.
