| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Homogeneities of a synthetic silica glass ingot were evaluated by the ultrasonic microspectroscopy technology. Specimens prepared from around the central axis of the ingot were heat-treated at desired annealing temperatures from 900 to 1150°C. Longitudinal velocities (Vl), leaky surface acoustic wave (LSAW) velocities (VLSAW), and densities (ρ) were measured to obtain relationships between acoustic properties and fictive temperatures Tf. Then, distributions of VLSAW and Vl were measured along the radial direction of the ingot. OH concentrations and Tf were measured by infrared spectroscopy. Optical retardations were also measured by optical heterodyne interferometry. From the results, we demonstrated that Tf distributions of glass ingot can be obtained by Vl measurements and variations caused by the residual stresses could be evaluated by VLSAW measurements. | |
