Abstract

A study was performed on chemical order lifetimes in liquids and a second fictive temperature for glassformers. The character of chemical order fluctuations in viscous liquids and their relation to the density and enthalpy fluctuations, determining the structural relaxation time and the glass transition temperature, were also discussed. It was found that in appropriate systems an increase in concentration of slow chemically ordering units in liquids could produce a crossover to fast ion conducting glass phenomenology.
