MÖSSBAUER EFFECT AND X-RAY DISTRIBUTION FUNCTION ANALYSIS IN COMPLEX Na2O-CaO-ZnO-Fe2O3-Al2O3-SiO2 GLASSES AND GLASS-CERAMICS

Mössbauer spectroscopy at room temperature has been carried out to determine the state of iron ions in complex glasses and glass ceramics in the SiO2-CaO-ZnO-Na2O-Fe2O3-Al2O3 system. Isomer shift values of the glasses suggest that Fe3+ and Fe2+ are in tetrahedral and octahedral coordination respecti...
