Abstract:The effect of high pressure and/or high temperature on the structure and mechanical properties of pyrope glass (Mg 3 Al 2 Si 3 O 12 ) was investigated. The local structure of the glass was characterized by the total pair distribution functions derived from synchrotron X-ray diffraction. The short-range order of the Si-O and Al-O pairs was not affected by densificationat 8 Gpa at room temperature. Small irreversible changes were observed in the intermediate range order of the glass, reflected in increasing dens… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
