Abstract

The glass formation is investigated and the highest contents of rare-earth oxides are determined in glasses of the Ln2O3–B2O3 system in the composition region (Ln2O3)1 + x · 3B2O3 (Ln = La, Nd, Gd, Er, Dy, Yb, Lu; 0 ≤ x ≤ 0.8). It is shown that the total content of rare-earth oxides in the La2O3Ln2O3–B2O3 ternary system can substantially exceed their highest content in the binary systems. The devitrification of glasses in the La2O3Ln2O3–B2O3 system at temperatures above the glass transition point Tg is analyzed.
