Abstract Si 3 N 4 ceramics with high mechanical properties and thermal conductivity, exhibiting fine bimodal microstructure, were prepared by adjusting the Er 2 O /MgO ratio hot‐pressing sintering at 1800°C for h. The grain distribution, lattice oxygen content, properties, crack propagation process of sintered bulk samples systematically investigated. It was found that a low contributed to densification ceramics, whereas favored growth ceramics. In this research, size distribution average diameters as well their impact on examined. When 3:1, had larger diameter higher but somewhat reduced. 2:2, sample displayed enhanced performance, which can be explained formation structure. research indicates it is feasible control microstructure optimize tailoring additives.

To solve the problem of deterioration oxidation resistance and thermal shock caused by low carbonization MgO–C refractories, nano-laminated BN modified graphite was prepared molten salt method to reinforce unfired refractories. The findings revealed that introduction significantly improved mechanical properties. Moreover, index refractories with 4 wt% 34% lower than unadded samples, residual strength after increased 224%. Furthermore, incorporating facilitated formation columnar Mg2SiO4, octagonal MgAl2O4, MgO–Mg2SiO4–MgAl2O4–Mg3B2O6 dense layers, thereby contribute overall performance improvements.

Abstract MgO–C refractories are of paramount importance in the converter side blowing system, requiring outstanding oxidation resistance under harsh conditions including high temperature, oxygen atmosphere, and high‐speed airflow. In this study, MgSiN 2 phase reconstruction was used to improve refractories, as well mechanical properties were evaluated. The results indicated that cold modulus rupture sample with 9 wt% increased by 93.3% compared without . After tests, index rate constant ( k ) reduced 38.9% 35.3%. Furthermore, incorporating facilitated formation layered dense structures consisting plate‐like Mg‐Sialon MgO–Mg SiO 4 –MgAl O This structural optimization effectively inhibited diffusion reaction within material, resulting gradual potential mitigation.
