Glass (plastic polymer) normally transforms to supercooled liquid (rubber) above the glass transition temperature (Tg). The transition causes the shape recovery effect. We have studied the shape recovery effect of SiO2 glass. The shape recovery effect was found in the temperature range from 770K to 1170K. The SiO2 glass can be a new actuator which can be operated at high temperature.
