The scope of application cerium dioxide and its special physical chemical properties are considered in the work. effect size factor on nanodispersed determines biological activity material, low toxicity high oxygen non-stoichiometry. Specific CeO2 include ability to regenerate non-stoichiometry, which is expressed nanoparticles return their initial state after participating redox process a rela...

IR, X-ray diffraction and thermal analysis were used to illustrate the structure of cerium and thorium laurate in solid state. IR results reveal that the fatty acid exists with dimeric structure through intermolecular hydrogen bonding and cerium and thorium laurate were ionic in nature. The X-Ray diffraction measurements confirm that these soaps posses double layer structure with long spacing. ...

In this work, the feasibility of employing Cyanex 923 as an extractant into the non-cerium REE (rare earth elements) impurity analysis of high-purity cerium oxide was investigated. Through investigations on the choice of the extraction medium, the optimium extraction acidity, matrix Ce4+ effect on the non-cerium REE ion extraction, the optimium extractant concentration and suitable extracting t...

Thermodynamic calculation has been applied to predict the inclusion formation in molten SS400 steel. When the Cerium addition in liquid iron is 70 ppm and the initial Oxygen and Sulphur are both 110 ppm, the formation of oxides containing Cerium would experience the transformation from Ce2O3 to CeO2 and also the formation of sulfides containing Cerium would experience the transformation from Ce...
