【Abstract】 The effects of mullitization of andalusite aggregate,additions of SiC and synthesized mullite and the firing temperature on property and microstructure of mullite-cordierite kiln furniture were studied.The results show that the mullitization effect of andalusite can improve the sintering property of the material markedly fired at 1380 ℃ for 4 h,and adding 4% SiC can improve the physical property of the materials.And also,adding some synthesized mullite can improve the physical property of the material by strengthening the structure of the material.更多还原
