Effects of Lanthanum on Structure of Sodium Borosilicate Glasses

Abstract

Nuclear waste management poses a significant challenge in contemporary society, necessitating innovative approaches for confinement and characterization. This chapter addresses the synthesis and characterization of a model glass intended for nuclear waste encapsulation. Specifically focusing on the incorporation of lanthanum into the glass matrix, we detail the synthesis procedures and investigate its structural and mechanical implications. Utilizing advanced spectroscopic techniques including X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), Raman spectroscopy, and Brillouin scattering, we elucidate the intricate interactions between lanthanum ions and the glass structure. This contribution not only enhances our fundamental understanding of nuclear glass compositions but also provides insights into the development of robust strategies for nuclear waste containment.
