Abstract

Using stainless steel slag and iron tailings as main raw materials, the CaO-MgO-Al₂O₃-SiO₂ (CMAS) glass-ceramics with a solid waste utilization rate exceeding 70 % was prepared, and the effects of Cr₂O₃ content on the nucleation and crystallization of glass-ceramics were investigated by X-Ray diffraction (XRD). Research indicates that the main crystalline phases of CMAS are all pyroxene, and the content of Cr₂O₃ increases in a certain range, which promote the crystallization ability of crystals in glass. Besides, the increase of Cr₂O₃ content within a certain rangepromotes the crystal crystallization in glass.
