This paper demonstrated a new approach to the utilization of steel slag and provided a pattern for steel slag ceramic synthesis. Based on previous research on steel slag (converter slag) applied as raw material of ceramic and directed at content of steel slag CaO-MgO-Al2O3(5wt%)-SiO2 system phase diagram was utilized in steel slag ceramic formula designing and augite region was selected. Bending strength of sample could reach 62.26MPa which was higher than national standard. When the content of steel slag was 40wt%, the steel slag ceramic would perform rather high bending strength. Through XRD patterns demonstrated the dominated crystal phases of all ceramic samples were pyroxene group crystals, akermanite existed in some samples also. But bending strengths of ceramics containing akermanite were lower than of samples containing pyroxene purely. Hence, diopside could be considered as the factor of improving ceramic bending strength.
