Abstract The Al₂O₃-MgAl₂O₄ composites are widely used in some special high-temperature industries due to their excellent properties, which arouses widespread attention. In this work, using bauxite and magnesia as raw materials, the Al₂O₃-MgAl₂O₄ composites was obtained by solid sintering process at 1 350—1 450 ℃ for 2 h, and then the effects of MgAl₂O₄ content and sintering temperature on its densification and mechanical properties were studied. The findings show that the sample has a good densification and mechanical property after sintering at 1 400 ℃ for 2 h, while the densification and mechanical property of the sample decrease when the sintering temperature increased to 1 450 ℃. With the mass ratio of MgAl₂O₄ to Al₂O₃+MgAl₂O₄ of 35∶100, the sample has the best performance, with a minimum apparent porosity of 0.64% and a flexural strength of 132.11 MPa.

Key words： composite MgAl₂O₄ ion diffusion mechanical property solid solution
