Abstract The method for preparing metal oxide nanometer material is characterized by that mixing and grinding metal salt and alkali metal hydroxide in ball-grinding mill to make them produce solid-solid phase transient chemical reaction, then using water to wash and dissolve, and remove alkali metal salt produced by said reaction, filtering and high-temp. roasting the metal oxide and metal hydroxide mixed filter care to make secondary reaction. The raw materials of said invented method are easily available, its operation is simple and reaction condition is moderate, technological process is simple and its coversion rate is about 100%, and its yield is high.
