The pressure (up to 2 GPa) and devitrification-induced properties and structural changes in glasses studied by an ultrasonic method are summarized. The pressure has a larger effect on the longitudinal mode for a crystallized state and on the shear mode for a glassy state in oxide glasses. The crystallization significantly affects the longitudinal mode for oxide glasses and the shear mode for metallic glasses. The different effects are contributed to their different microstructures in short-range order for different glasses. © 2003 American Institute of Physics.

The photosensitivity arises from the cerium in the glass. After...
