Er3+/Yb3+ doped 22[3SrO.2TiO2].30 [2sIo2.B2O3] glass and glass-ceramics are developed and investigated for their electrical properties. The degree of crystallization is varied by means of crystallisation temperature ranging from 600-1000 deg C. In glass-ceramic samples, two major crystalline phases, Sr3Ti2O7 and TiO2, are confirmed by diffraction analysis. The best crystallized glass-ceramic sample shows 100-1 50 times lower impedance in temperature range, 200-300 deg C, than the uncrystallized glass. Electrical relaxation corresponding tot he crystalline phase can be isolated in frequency domain.
