Abstract
Abstract Giving emphasis to electrical transport in the thermally unstable region, a conditional glass former based system 50Li 2 O–(50-x)P 2 O 5 –xMoO 3 is investigated. Though glass forming region is narrow, the electrical conductivity exhibits significant rise up to x ≤ 15 mol%. Scanning electron microscopy investigations suggest existence of tiny crystallites well separated by glass tissues for higher MoO 3 content samples. It is therefore revealed that addition of MoO 3 improves the thermal stability. Electronic conductivity in this system is found to be fairly low and suggests phonon assisted polaron hopping. Electrical conductivity is found to be comparable to glass and glass-ceramic samples.
