Abstract

The structure of a ternary 40AlF3 · 20YF3 · 40CaF2 glass (AYC glass) was examined by a combination of X-ray and neutron diffraction analysis and molecular dynamics simulations. The comparison with the structure of 40AlF3 · 20BaF2 · 40CaF2 glass (ABC glass) [T. Nanba et al., Mater. Sci. Forum 32&33 (1988) 385] indicated that the network structures of both glasses were similar to each other, with AlF6 octahedra joining at their corners to form chains with branches. Although AlF7 polyhedra were not found in ABC glass, they existed in AYC glass, as one third of the AlF6 octahedra, and these polyhedra were distorted due to the presence of Y3+ ions.
