Structure And Properties Of Ga203 Based Glasses

Glass formation, structure and some basic, topical properties have been reviewed for gallium oxide-based systems which are free from conventional glass-forming oxides. Glass-forming tendency is unexpectedly large for Ga203-based systems. In binary and ternary systems, it is especially large for heavier metal oxides. Diffraction and spectroscopic studies indicate that all or most of Ga3+ ions are four-coordinated, not six-coordinated, which confirms Zachariasen's rule for glass formation.
