主　　题：andalusite mullile α - A12 O3 refractory micropawder 

摘      要：Mullite refractory was made from micropowder of andalusite and α-M2O3 by an one-step sintering process . This refractory has a lower linear expansion coefficient, more simple process and the sintering tem-parature can be decreased 200 - 25017 . But the cool strength of the material is near to that of fused casting mullite brick. For this material, the test sum of α-Al2 O3 added is 20% , the favorable sintering temperature is 1400℃.
