摘　　要：本文以镁渣、高岭土、工业氧化铝为原料,采用高温固相法制备C2AS-CAS2复相耐火材料,利用XRD、FE-SEM、EDS等测试技术对试样进行表征,并测试了试样的耐压强度、抗水化性能、抗热震性能。结果表明,试样主晶相为C2AS和CAS2,耐压强度为65.3 MPa,抗水化性能及抗热震性能良好。To make full use of magnesium slags,the C2AS-CAS2 composite refractory was sintered by using magnesium slags, kaolin and A1203 at normal pressure. The phases, microscopy, compressive strength, size deviation, thermal shock and anti-hydration property of samples were analyzed by XRD, FE-SEM, EDS, mechanical testing and others techniques. The results show that the main phases of the samples are C2AS and CAS2;the compressive strength is up to 65.3 Mpa;the samples have well anti-hydration property and thermal shock resistance.
