Paper Abstract

The thermal relaxation of the tellurium halide based glasses has been studied at different temperatures. It was found that some of these glasses can be appreciably relaxed at room temperature and the glass transition temperature increases significantly. It is always possible to increase Tg of all these glasses by appropriate heat treatment. The fictive temperatures as a function of annealing time have been determined for several glasses. This study allows to optimize the heat treatment.
