Abstract

A Debye temperature θD of 378 (±5K) has been obtained by applying a simplified Debye model to the57Fe Mössbauer spectra of 60CaO·39Ga2O3·57Fe2O3 glass. The θD value is comparable to those (280–580 K) obtained so far in several oxide glasses, glass-ceramics, and ceramics in which Mössbauer atoms are covalently bonded to oxygen atoms and play a role of network former. It proves that Fe(III) atoms occupy the substitutional sites of Ga(III) constituting distorted GaO4 tetrahedra.
