MgO was considered to be indispensable mineral composition of modern sintering process. Fluidity of liquid phase reflecting the scope of effective bonding makes a clear distinction among MgO-bearing fluxes in the sintering process. Mg-Ca combination forms of Dolomite, l-dolomite, serpentine and their influence on the fluidity of liquid phase and bonding strength of sinter body were investigated and analyzed. The results showed that there were non-separated, partly-separated, completely-separated states of Mg-Ca in different MgO-bearing fluxes. Furthermore, development of the separation degree of Mg-Ca combined states led to the decrease of Mg content melt in silico-ferrite of calcium and aluminium (SFCA) and increase of Mg content in magnetite. Consequently, fluidity of liquid phase was improved due to decline of viscosity of liquid phase. Moreover, bonding strength had a good positive correlation with fluidity of liquid phase. Hence, increase of Mg-Ca separated degree was beneficial for improvement of fluidity of bonding strength.
