Abstract: PROBLEM TO BE SOLVED: To provide cerium dioxide nanoparticles CeMOincluding at least one transition metal (M) and a method for preparing such particles.SOLUTION: In a process for forming cerium dioxide nanoparticles including at least one transition metal (M), a product flow including transition metal-containing cerium dioxide nanoparticles CeMO(x bears a value of approximately 0.3 to approximately 0.8) is generated by using a suspension of cerium hydroxide nanoparticles prepared by mechanically shearing an aqueous admixture including an oxidant at an amount effective for oxidizing trivalent cerium ions into tetravalent cerium ions. The nanoparticles thus obtained have a cubic fluorite-type structure, an average rheological diameter of approximately 1 to approximately 10 nm, and a geometric diameter of less than approximately 4 nm. A particle dispersion system within a non-polar medium can be prepared by using transition metal-containing crystalline cerium dioxide nanoparticles.

Abstract: A process for making cerium dioxide nanoparticles containing at least one transition metal (M) utilizing a suspension of cerium hydroxide nanoparticles prepared by mechanical shearing of an aqueous mixture containing an oxidant in an amount effective to enable oxidation of cerous ion to eerie ion, thereby forming a product stream that contains transition metal-containing cerium dioxide nanoparticles, Cel-xMxO2, wherein "x" has a value from about 0.3 to about 0.8. The nanoparticles thus obtained have a cubic fluorite structure, a mean hydrodynamic diameter in the range of about 1 nm to about 10 nm, and a geometric diameter of less than about 4 run. The transition metal-containing crystalline cerium dioxide nanoparticles can be used to prepare a dispersion of the particles in a nonpolar medium.
