Coupled Experimental Study and Thermodynamic Modeling of GeO2 and GeO2–CaO and GeO2–SiO2 Binary Systems

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 2, February 2026.
ABSTRACT The phase diagram of the GeO2–CaO system was investigated using differential thermal–thermogravimetric analysis and the equilibration–quenching technique, followed by electron probe microanalysis and X‐ray diffraction. The Ca2Ge7O16 compound was confirmed to be stable, and a eutectic reaction of L → GeO2(hex) + Ca2Ge7O16 was identified in the ...
