摘　　要：以MgO -Al2 O3-SiO2 三元相图为依据 ,在M2 A2 S5-A3S2 连线上进行了堇青石 -莫来石复相材料组成点的设计 ,并在高温下合成了堇青石与莫来石比例为 1∶1的复相材料。重点讨论了烧成温度对堇青石一莫来石复相材料中堇青石、莫来石生成量的影响。XRD定量分析结果表明 ,当合成温度范围约在 1 380～1 4 2 0℃之间时 。Cordierte-mullite composites containing theoretical contents, whose compositions were designed on the line between M 2A 2S 5 and A 3S 2, were synthesized on the basis of MgO-Al 2O 3-SiO 2 system. Effects of sintering temperature on contents of cordierite and mullite of cordierte-mullite composites were discussed in detail. The results shown that composites containing theoretical contents were achieved when temperature ranged from l380℃ to l420℃.
