发明名称 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.
