In this paper, samples of xCeO 2 ·(100-x) (SiO 2 ·Al 2 O 3 ·CaO) (x: 0∼15) glass solidified body was prepared by a high temperature melting method. The structural characteristics and thermal stability of CeO 2 silicate glass-cured bodies were characterized by means of density porosity test, XRD, Raman, DSC and SEM. The results show that the addition of CeO 2 does not change the basic structure of the glass, which is located in the pores of the silicate glass grid and plays a network modification role. When the added amount is less than 5% wt, homogeneous glass is easily formed. CeO 2 is uniformly distributed in the glass body, and no enrichment occurs. When the added amount is more than 8% wt, CeO 2 easily crystallizes during cooling.
