Effect of B2O3 on Structure and Leaching Resistance of Borosilicate Glass
摘要
Abstract
Borosilicate glass for vitrification of high level nuclear waste (HLW) were prepared with SiO2,Al2O3,B2O3,CaO,Na2O and 5wt％ CeO2 by conventional solid-state method.The chemical durability of the glass waste forms was measured hy Product Consistency Test (PCT) and the leaching rate was analyzed via inductively coupled plasma mass spectra.Fourier turning infrared spectroscopy and Laser Raman spectroscopy were also used in order to analyze the structure of glass waste forms.The results show that [SiO4],[BO3] and [BO4] exist in the glass waste forms and some [BO4] turn into [BO3] as B2O33 content increases.The glass matrix has the highest glass transition temperature and the best normalized leaching rate of Ce when doped with 15.79wt％ B2O3.关键词
