Abstract:CaO-Al_2O_3-SiO_2 glass-ceramics were prepared using iron and steel slag as the major material and CaF_2, Fe_2O_3, Cr_2O_3, ZrO_2 as the multi-nucleation agent. Phase compositions and technical parameters were discussed by DTA, XRD and SEM. The principal physical and chemical properities of the glass-ceramics were tested and the mechanism of the nucleating agent, properties, technical parameters were investigated. The XRD results show that the main crystal phases of the glass-ceramics are Ca(Mg,Fe,Al) (Si,Al)_2O_6] and CaMg(SiO_3)_2]. The material shows a good chemical stability and has a density of 3.02g/cm 3, water absorption less than 0.04% and bending strength of 250MPa.
Keywords:iron and steel slag glass-ceramic nucleating agent
