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.
