A new method of oxides synthesis by detonation is proposed and its mechanism will be investigated also in this project. In order to study the mechanism of detonation synthesis respectively, the detonation synthesis is divided into the detonation ionization reaction, detonation pyrolytic reaction, high or low temperature type complex oxides in virtue of detonation experiments by using representative raw materials to synthesize nanometer powders, like alumina, titanium oxide, aluminates and lithium manganates.
