Av. Cardoso et al., IDENTIFICATION OF CRYSTALLINE PHASES FOUND IN MULTICOMPONENT ALF3-BASED GLASSES, Journal of non-crystalline solids, 161, 1993, pp. 56-59
Glasses in the system AlF3-[MgF2-CaF2-SrF2-BaF2]-YF3 (i.e., AMCSBY) ha
ve been optimised to reduce devitrification on quenching the melt. Cas
t specimens are in large part crystal-free. Nevertheless, microcrystal
lites tend to be present in a characteristic distribution within the g
lass bulk. The morphology and identity of these crystals are discussed
especially in relation to the crystallisation which occurs on reheati
ng the glass.
