摘要

This study examines the physical and mechanical properties of corundum ceramics fabricated from domestically sourced G-00 grade alumina. The optimal mechanical strength was achieved in ceramics sintered at 1450°C with the addition of 5 wt.% yttrium oxide and 5 wt.% of a eutectic MnO–TiO2 additive. The findings indicate the feasibility of import substitution of alumina.
