The results show that the microscopic structure of synthesized A12O, ceramics layer is mainly composed by ceramic phase AM), arid a little of a -ferrite and spinel phase Al2O-,-FeO in A14e2O, self-propagating high-temperature synthesis system.

• 研究结果表明,在Al/Fe2O3自蔓延高温合成体系中,合成的Al2O3陶瓷的显微组织主要为Al2O3陶瓷相和少量的铁素体与尖晶石相Al2O3·FeO;
