Effects of Melting Conditions on Cerium Oxidation State and Catalytic Properties of CeO₂–P₂O₅ Glass Systems

Preparation and physical properties of CeO2 doped and modified epoxy resin composites

“…The modified n‐CeO 2 spectrum exhibited the characteristic absorption peaks of both stearic acid and n‐CeO 2 at 2917, 2843, 1531, and 1248 cm −1 , respectively 37 . However, the peak positions were shifted to different extents, possibly due to the formation of coordination bonds or electrostatic bonds between the carboxyl group of stearic acid and Ce 3+ or Ce 4+ ions on the surface of n‐CeO 2 36,38 …”

“…81‐0792), indicating high crystallinity and no inhomogeneity. The results showed that the carboxyl group of stearic acid formed coordination bonds or electrostatic bonds with Ce 3+ or Ce 4+ ions on the surface of n‐CeO 2 without affecting the crystal structure of n‐CeO 2 36,39,40 …”

“…The results showed that the carboxyl group of stearic acid formed coordination bonds or electrostatic bonds with Ce 3+ or Ce 4+ ions on the surface of n-CeO 2 without affecting the crystal structure of n-CeO 2 . 36,39,40 The TEM images of n-CeO 2 nanoparticles before and after modification with 3 wt% SA were displayed in Figure 5. The images revealed that the dispersion of surface-modified n-CeO 2 was better than the unmodified n-CeO 2 .…”

Improving structure and properties of lead phosphate glass through precipitation of few crystals from CeO2

“…It was reported previously that some specific types of rear earth oxides such as CeO2 and Nd2O3 have dominant influences on the structure, mechanical and magnetic properties of glasses and glass ceramics [1][2][3][4][5]. A number of previous studies have been performed to shed some light on the practical and manufactured uses of glasses containing cerium oxide [6].…”

“…In addition, cerium oxide, which has been reported to be used as decolorizing glass and eye protective glasses [6,7], has been further commercially used since it has been established that cerium has a clear use, depending on its material, as an excellent ultra-violet absorption. Recently, several experimental results have been carried out on cerium silicate [8] and borate glasses [9], suggesting that CeO2 enters the host glass network as an intermediate, both as a glass modifier and as a former at normal circumstances [1][2][3][4]8,9]. Under excessive conditions, such as exposure the glass to irradiation processes, the irradiated glass becomes unusable for optical applications.…”
