Direct-current conductivities of mixed-alkali Na/sub 2/O-K/sub 2/O-GeO/sub 2/ glasses with about 0.02 mol% total alkali were investigated. No minima in conductivity isotherms were indicated as K/sub 2/O is substituted for Na/sub 2/O. However, a conductivity-suppressing effect with the addition of K/sub 2/O to Na/sub 2/O-GeO/sub 2/ glass was demonstrated, from the comparison with the conductivity of Na/sub 2/O-GeO/sub 2/ glasses of varied sodium content (0.0079 approximately 0.30 mol% Na/sub 2/O). 10 refs.
