Claim Text:
1. A method for making a dispersion of cerium oxide nanoparticles that include at least one other metal, comprising: forming an aqueous reaction mixture comprising: a source of cerous ion and a source of one or more metal ions other than cerium; a source of hydroxide ion; at least one monoether carboxylic acid, wherein the molar ratio of said monoether carboxylic acid to total metal ions is greater than 0.2; and an oxidant; oxidizing the cerous ion to ceric ion; and thereby forming in the reaction mixture a dispersion of metal-containing cerium oxide nanoparticles, Ce
