The effect of mechanical milling and two-step sintering technique on the microstructure, microhardness, strength, and dielectric properties of Sm2Zr2O7 ceramics by I.E. Kenzhina, A.L. Kozlovskiy, R.I. Shakirzyanov, M.E. Kaliyekperov, N.O. Volodina, S.A. Maznykh, M. Begentayev, S.K. Askerbekov, Zh.A. Zaurbekova, A.U. Tolenova, P.A. Blynskiy

“…Despite differences in microstructure and grain size distribution, both the sample sintered at 1350 °C for 20 hours and the one sintered at 1700 °C for 10 minutes exhibited the highest mechanical properties, with microhardness values HV1 ∼1200 and biaxial flexural strength reaching ∼125 MPa. This suggests that the enhancement of mechanical performance may be linked to a reduction in internal stresses, either due to the elevated temperature during the first sintering step or the extended holding time during the second step. …”
