![]() ![]() X-ray diffraction results were good consistent with the simulation results. Then, the formula with a slag content of 40wt% was selected and optimized. This is because increasing magnesium can promote the formation of pyroxene. When the slag ratio is above 45wt%, pyroxene is generated more than anorthite. The simulation results indicate that mullite is generated but drastically reduced at the slag ratios of 0–25wt%, and anorthite is the dominant crystalline phase in the slag content of 25wt%-45wt%. In this paper, a series of ceramics with different slag ratios (0–70wt%) were designed, and the software FACTsage was introduced to simulate the formation of crystalline phases. However, the relationship among the initial composition, ceramic microstructure, and macroscopic properties requires further study. Abstract Using steel slag as a main raw material of ceramics is considered as a high value-added way.
