| Outline of Final Research Achievements |
We succeeded to develop a new technique obtaining viscosity of high-temperature liquids, molten oxides and allots melts, using the resonant droplet oscillation. Using the technique, we obtained high and low viscosity of molten oxides in wide temperature range. From obtained viscosity, we discussed the glass forming ability from the relationship between logarithm viscosity and the normalized temperature by glass transition temperature. From the research works should be contributed to materials science and industrial material processing.
