摘要： An object of the present invention is to easily obtain zirconium oxide particles that contain a metallic element such as a rare earth oxide (preferably stabilized with a metallic element) and exhibit good dispersibility in organic media, without using an aqueous sulfate solution such as an aqueous solution of MgSO4, or using a reduced amount of the aqueous sulfate solution. The present invention is a zirconium oxide nanoparticle coated with a first carboxylic acid that is at least one of primary carboxylic acids and secondary carboxylic acids and has 3 or more carbon atoms, wherein the zirconium oxide nanoparticle comprises at least one selected from the group M consisting of rare earth elements, Al, Fe, Co, Sn, Zn, In, Bi, Mn, Ni, and Cu.
