Structural relaxation studies during annealing of a series of ZrF4-based glasses below the glass transition temperature have been carried out. Indications are that no property changes due to structural relaxation are likely to occur at ambient temperature over periods of tens of years. Some of the lower Tg glasses, however, did exhibit detectable structural relaxation on annealing at temperatures as low as 100°C over roughly a one year time period.
