A new method is put forward to prepare nanometer zirconia base solid solution by exothermal solid‐state synthesis. This method is realized by agitating solid mixture of sodium hydroxide, zirconium oxychloride, and yttrium/calcium nitride. Fresh and final powders are studied by X‐ray fluorescence, X‐ray photoemission spectroscopy, X‐ray diffraction, and transmission electron microscopy. The results show the obtained tetragonal/cubic zirconia solid solution nanopowders are highly pure and distribute around 5 nm. It is suggested that the coordinated water of zirconium oxychloride acts as micro medium and the nuclei of solid solution are formed under the superalkaline environment and grow during heat treatment. This method may be useful to prepare other metal oxide nanopowders.
