Survival of Fragmented BO₄ Units in Highly Modified Rare-Earth-Rich Borate Glasses.

ABSTRACT: Highly modified La₂O₃-Y₂O₃-B₂O₃ ternary glasses were fabricated by using a levitation technique. The thermal and structural properties of (50 - x)La₂O₃-xY₂O₃-50B₂O₃ glasses and (60 - y)La₂O₃-yY₂O₃-40B₂O₃ glasses were investigated. Raman scattering spectra indicated that B atoms mainly formed isolated planar BO₃ triangles similar to those of crystalline LaBO₃. This process was independent of the ratio of La₂O₃ and Y₂O₃. ¹¹B magic angle spinning nuclear magnetic resonance spectra confirmed that
