Ferronickel slag can be used for refractory material production by sintering it with the addition of sintered magnesia in the microwave field. In this study, the influence of microwave sintering temperature and time on the refractoriness and mechanical properties of materials was assessed by contrasting the phase transformations and microstructure changes of samples obtained at different sintering temperatures and time on the premise of fully considering the thermodynamics properties of the raw materials. It was shown that the high quality refractory material with refractoriness over 1750 °C and bulk density over 2.65 g/cm3 was obtained when the sample was sintered at 1300 °C for 20 min. The exploration of sintering temperature and time has good potential in enhancing the quality of refractory material, providing a new approach for the effective and efficient recovery and utilization of ferronickel slag and other related industrial waste.
