Process for the preparation of perovskites on the basis of manganese or chromium and perovskites so obtained. |
摘要 |
The invention relates to compositions based on manganese or chromium perovskites. These compositions have a chemical homogeneity such that the heterogeneity domains are at most 1 mu m<3>. They are obtained by a process characterized in that a mixture is formed comprising salts and/or sols of the constituent elements of the composition, the said mixture is dried and the dried product is calcined. |
