Research Abstract |
Isotope substitution is a powerful tool to clarify the nature of the properties of glass because it changes atomic mass without changing its atomic size or electronegativity. In this study, boron isotope effects on the thermal properties and viscosity of oxide glass are investigated. Isotope mixing is found to decrease the thermal conduction of glass. It also found to decrease the viscosity of glass melt. These phenomena will be related to the localization of atomic vibration by isotope mixing. In addition, these results show that the isotope substitution is a powerful tooltocontrolthepropertyofglass.
