Ternary lithium borotellurite glasses of composition(Li2O)y[(2TeO2)x-(B2O3)1−x](1−y) (y=0.33 and 0.40; and 0≤x≤1) reveal a negative network former mixing effect, implying that their electrical conductivities and ionic mobilities are lower than those expected by linear interpolation between their bin...
