摘　　要：在纯铝热剂(Al+Fe2O3)的基础上,研究了稀土氧化物、炉渣添加剂对金属基陶瓷内衬微观组织及结构的影响。实验结果表明,加入5%的炉渣不改变陶瓷层的组织组成,稀土氧化物的添加能够促进Al2O3的枝晶化和组织细化,有利于提高陶瓷层的致密度。This article studied the effect of rare earth oxides and slag additives on the microstructure of the ce-ramic-lined compound pipe based on the pure of thermite（Al＋Fe2O3）. The result indicated that the structure of ce-ramic layer was not changed by 5% slag additive, but the rare earth oxides additive can accelerate the arborescent crystallization and the fabric refinement of Al2O3, thus the density and stain resistant of the ceramic layer is en-hanced.
