The feasibility of a technological route for preparing refractory materials from a ferronickel slag was verified in this study. Based on the thermodynamics analysis, the effect of the roasting temperature on the development of refractory material from the slag was studied in the presence of magnesia. The results of thermodynamics calculation showed that the reaction of MgO with SiO2 generated forsterite and enstatite, whereas the reaction between o MgO and Fe2O3/Al2O3 produced corresponding magnesia spinels. The experimental results showed that a refractory material with refractoriness of above 1580 °C, bulk density of 2.88 g/cm3, compressive strength of 106.9 MPa, and apparent porosity of 5.8% were obtained under the conditions of magnesia addition of 15%, roasting temperature of 1350°C and roasting time of 3 h. With increasing roasting temperature, the bulk density and the compressive strength of refractory material increased but the apparent porosity decreased.
