%X Cerium oxide has a great capacity to remove nonbridging oxygen atoms (NBO) from the glass network and serves as glass former units. The well formed CeO<sub>4</sub> units played the role of decreasing NBO from the silicate network and cause a reduction in the concentration of tetrahedral boron groups (N<sub>4</sub>). The highest content of NBO in glass of lower CeO<sub>2</sub> (1 mol%) has a dominant role in constructing crystalline clusters in the glass. Higher CeO<sub>2</sub> concentration leads to formation of an amorphous glass network as documented by XRD and TEM-EDP spectra. Coordination of cerium with oxygen atoms gives uniform units of spherical morphology in the pure CeO<sub>2</sub> as well as in cerium rich glass. Clustered species has a great benefit in the field of application, used as a shielding material for ionized radiations.
