Müller, Dirk; Hess, Kai-Uwe und Dingwell, Donald Bruce (2022): A tetrad effect in the glass transition of lanthanide-doped sodium disilicate glasses. In: Journal of the American Ceramic Society, Bd. 105, Nr. 6: S. 3725-3728

Abstract

Scanning calorimetric determination of the glass transition temperatures (T-g) of sodium disilicate doped individually with 25 wt.% of the oxides of La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu reveals the presence of the so-called lanthanide tetrad effect in their glass transition temperatures. This is to the best of our knowledge the first observation of a tetrad effect in the macroscopic properties of a high-temperature silicate phase.
