BILLE MAGNETIQUE
The invention relates to a sintered ball that has the following crystallized phases, in mass percentages based on crystallized phases and for a total of 100%: stabilized zirconia: remainder up to 100%; monoclinic zirconia: ≤20%; 4%≤magnetic component≤22%; crystallized phases other than stabilized zirconia, monoclinic zirconia and magnetic component: <10%; the magnetic component being chosen from among magnetic spinels, magnetic garnets, magnetic hexagonal ferrites and mixtures thereof; the sintered ball comprising, in addition to the magnetic component, CeO2 and optionally Y2O3, in contents that, in molar percentages on the basis of the sum of ZrO2, CeO2 and Y2O3, 3%≤CeO2≤17.5% and 1.5%≤Y2O3+(CeO2)/3.5≤5%.
