High Temperature Raman Spectra of Li₂O-P₂O₅ Melts with Large Amounts of Li₂O

Abstract

Proportion of metaphosphate, pyrophosphate, and orthophosphate in Li₂O-P₂O₅ melts containing large amounts of Li₂O were estimated by high temperature Raman spectra. The change in proportion of each structural unit with composition in melts was similar to that in rapidly-quenched glasses, though the proportions of metaphosphate and orthophosphate groups were somewhat higher in melts than in glasses.
