| 摘要 |
The invention relates to a porous structure including an oxide ceramic material comprising, on the basis of the corresponding simple oxides: Al2O3; TiO2; at least one oxide of an element, M2,selected from the group containing Fe2O3, Cr2O3, MnO2, La2O3, Y2O3, Ga2O3; at least one oxide of an element, M3, selected from the group containing ZrO2, Ce2O3, HfO2; andoptionally at least one oxide of an element, M1, selected from among MgO, CoO and optionally SiO2, said material being obtained by the reactive sintering of the corresponding simple oxides or one of the precursors thereof or by the heat treatment of sintered grains having said composition. |
