Although ozone is a strong oxidizing agent, few researches have been using it for inorganic syntheses. In this project, the oxidation method for metal oxides by ozone has been established, and CaFeO3, which needs heating under the oxygen pressure of at least 20,000 atm, has been successfully synthesized for the first time. Furthermore, by applying this method, new Fe4+-perovskites, cubic BaFeO3, and Sr1-xBaxFeO3 solid solution have been also successfully prepared.

臭氧是一种强氧化剂，但将其用于无机合成的研究却很少。在该项目中，建立了通过臭氧氧化金属氧化物的方法，并首次成功合成了需要在至少20，000 atm的氧气压力下加热的CaFeO 3。此外，还成功地制备了新型的Fe ~（4+）-钙钛矿、立方相BaFeO_3和Sr ~（1-x）-FeO_3固溶体。
