Abstract

Mullite–cordierite saggar materials commonly used in the industry are easily corroded by LiNi_xCo_yMn₁₋_x_–_yO₂ (LNCM) materials during the synthesis of Li-ion batteries. To extend their service life, the influence of varying the proportion of calcium hexaluminate (CA₆) ranging from 0 to 12 wt% on the sintering behavior of the mullite–cordierite system was investigated. These samples were then tested to evaluate their physical characteristics, resistance to corrosion by LNCM materials, and thermal shock stability. The experimental results show that the open-pore structure formed by the interstacking grains of CA₆ effectively impedes further penetration of the corrosion phase. Moreover, the addition of CA₆ resulted in the in situ formation of anorthite within the material, enhancing its sintering and bonding properties and significantly improving the material's corrosion resistance. Consequently, incorporating CA₆ effectively enhances the saggar's thermal shock stability and corrosion resistance.
