Exploring entropic contributions of modifier cations in supercooled liquids through isotopic substitution

Journal of the American Ceramic Society, Volume 108, Issue 12, December 2025.
Evolution of excess entropy of 7(6)LiPO3 supercooled liquid (SCL) between Tg and Tm Abstract The vibrational and configurational entropic contributions of modifier Li cations to the glass‐to‐liquid transition and the fragility of supercooled (Li,Na)PO3 liquids are investigated using calorimetric measurements of their ⁷Li and ⁶Li isotopologues ...
