Abstract

Abstract

Fe/Fe₂SiO₄-based cermets were prepared with magnetic separation iron concentrate as the main raw material and kaolin as the additive by means of microwave in-situ reduction. The theoretical basis, main technical route, and reaction mechanism of iron-based cermets developed by using microwave heating in situ reductions of magnetic separation iron concentrates are summarized. Combined with XRD, SEM, and other analysis and testing methods, the effect of kaolin content on phase, physical properties, and microstructure of iron-based cermets composites had been explored. The results show that under conditions of Kaolin content at 15%, sintering at 835 ℃ for 1 hour can make iron-based cermets composites achieve the best comprehensive properties, where dominant phase is α-Fe, its density is 5.56 g/cm³, and Vickers hardness is 7.35 GPa.
