xLi2O · (100 − x)SiO2 phases, where x = 20, 25, 33, 40, 50, 55, and 60 mol % (hereinafter, Li20, Li25, Li33, Li40, Li50, Li55, and Li60) were crystallized from melts, and their qualitative composition was determined by X-ray diffraction. The Li6Si2O7 phase was established to precipitate during the crystallization of the melt containing 60 mol % Li2O, thus enabling us to locate characteristic bands in the IR and Raman spectra of lithium pyrosilicate.
