Abstract: In order to increase the resource utilization rate of iron-rich waste residues and produce functional high value-added products, the research progress of glass-ceramics from iron-rich waste residues in recent years was reviewed, covering the materials with non-magnetic and magnetic properties. The composition-structure-properties-application interrelationships of the  iron-rich  glass-ceramics  are  systematically  elaborated.  For  the  non-magnetic  iron-rich  glass-ceramics,  the  effects  of sintering atmosphere and iron ion valence on the structure and properties will be summarized. For the magnetic iron-rich glass-ceramics, three representative materials, i.e., magnetite-based, bariumferrite-based and zincferrite-based glass-ceramics, will be  introduced. Especially, the  effect  of iron  oxide  on the  structure  and properties  of magnetite-based  glass-ceramics will be explored. Finally, the problems of single function of iron-rich glass-ceramics and the lack of theoretical studies are pointed out and the research direction of iron-rich glass-ceramics is prospected.
