A mullite-cordierite saggar was prepared with mullite, cordierite, α-Al2O3, talc and Kaolin clay, and the room-temperature mechanical properties, thermal shock resistance and erosion mechanism of saggar in sintering process of LiCoO2 were investigated. The results show that the better mechanical properties and thermal shock resistance of the saggar can be obtained when sintering at 1 350 ℃. The bending strength of sample is 11.18 MPa and its residual strength retention rate after three cycles of thermal shock is 44.8%. In the process of sintering LiCoO2, a mullite-cordierite saggar is attacked by Li2O, producing LiAlSiO4, Li4SiO4 and LiAlO2. Li2O diffuses into the sagger along the pores, and the structure of the permeation layer is denser after the reaction, which can hinder Li2O from further attacking the sagger, thus giving a good erosion resistance of mullite-cordierite sagger.
