A sintered material exhibiting the following chemical composition, as percentages by weight: iron oxide(s), expressed in the Fe2O3 form, ≥85%, CaO: 0.1%-6%, SiO2: 0.1%-6%, 0.05% ≤TiO2, 0≤Al2O3, TiO2+Al2O3≤3%, and constituents other than iron oxides, CaO, SiO2, TiO2 and Al2O3: ≤5%. The CaO/SiO2 ratio by weight is between 0.2 and 7. The TiO2/CaO ratio by weight is between 0.2 and 1.5. |
