In recent years, use the steel slag and fly ash processed into crystallite glass, in overseas has been widely used in architectural decoration materials, but because the domestic technology and preparation technology of the defects in its cost is exorbitant, no extensively, therefore has the necessary to further research on. In order to reduce cost, improve quality. In this paper the development situation of glass-ceramics preparation methods and their applications were reviewed with system; And with steel slag and fly ash as the main raw material, using the orthogonal design method of selecting a suitable microlite glass formula composition to CaF2 and TiO2 as the composite nucleation agent, prepared by melting with CaO - legal Al2O3 - for the system, main SiO2 crystalling phase for through pyroxene(Ca(Fe,Al)(Si,Al)2O6) of microcrystalline glass. Using X-ray diffraction (XRD), scanning electron microscopy (SEM) and other modern testing method of preparation, the crystallite glass sample content phase composition, microstructure and crystal structure were studied. The results show that the steel slag and
