Abstract: As a novel multiphase material used in the high temperature material field in recent years, ferrosilicon nitride is mainly composed of silicon nitride and ferrosilicon. Since the 1970s, the ferrosilicon nitride has shown the good performance using as the blast furnace materials, but the excessive preparation cost has greatly restricted its further development. In the 1990s, the industrialized preparation of cost-effective ferrosilicon nitride was realized by flash-combustion synthesis technology developed by the Laboratory of Inorganic Non-Metallic Structural Materials, University of Science and Technology Beijing, which promoted the research and popularization of ferrosilicon nitride materials. In addition to the taphole clay, the ferrosilicon nitride has also shown the good performance used as castables. The preparation, structure, and properties of ferrosilicon nitride were introduced in this paper, the reaction mechanism of flash-combustion synthesis was analyzed, the performance and application of ferrosilicon nitride in different environments were summarized, and the research direction and potential applications of ferrosilicon nitride materials were prospected.
