Abstract

Ultrasonic microspectroscopy technology was applied to characterization of synthetic silica glasses. Acoustic properties (longitudinal and shear velocities, leaky surface acoustic wave velocity, and density), fictive temperature T_f, chlorine concentration C(Cl), and OH concentration C(OH) were measured, and related relationships among their properties were discussed. The longitudinal velocities in the acoustic properties have the highest sensitivities of 5.93Â°C/(m/s), -202 wtppm/(m/s), and -31 wtppm/(m/s), with resolutions of 0.6Â°C, 20 wtppm, and 3.1 wtppm, to T_f, C(Cl), and C(OH), respectively. The variations in the acoustic velocities due to T_f, C(Cl), and C(OH) are mainly caused by variations in elastic constants, except for shear velocity due to C(OH).
