Abstract
Low melting point glass are attractive industrial materials due to their high thermal and chemical resistance compared to conventional glass. our study aimed to study the influence of transition oxides such as Fe2O3 and Cr2O3 on the thermal and the magnetic properties of glass. The results of differential scanning calorimetry (DSC) have provided a lot of essential information on the correlation between the chemical composition of glass and their characteristic parameters, such as glass transition temperature, crystallization temperature, melting temperature. We have performed the measurement of X-ray diffraction, IR and RAMAN, Mössbauer spectroscopy, as well as the measurements of density, dissolution rate and activation energy of dissolution. The proportion on transition oxides in the sudied glass ensure the glass thermal stability, the relatively low melting temperature, and a high chemical durabilité, with application potential in nuclear waste immobilization.
