Abstract Developing low‐carbon and high‐performance Al 2 O 3 –C refractories is vital for extending the service life of slide gate plate reducing carbon emissions. In this study, hexagonal boron nitride (h‐BN) composite powder was prepared using magnesiothermic reduction combustion synthesis route introduced into refractories. The phases composition, microstructure, mechanical properties, thermal shock, slag corrosion resistance were investigated. results show that shock enhanced by adding h‐BN powder. Due to h‐BN, consequent in situ formed spinel AlN whiskers, crack propagation deflected, branched forming more fine cracks, then enhanced. addition chemical inertness decrease pore size plays an important role enhancing synthesized via study demonstrated potential application plates used continuous casting technology.

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.
