A new CaO-Al2O3-SiO2 glass-ceramics were prepared using natural cooling titanium blast furnace slag,and the effects of different systems of nucleating agents on the crystallization,microstructure and properties of the glass-ceramics were also studied by DSC,XRD,SEM,etc.The results indicate that highperformance glass-ceramics could be obtained by adding a large amount of titanium blast furnace slag(> 60%),and the moderate concentration of CaO and higher TiO2 content in this slag serve as effective constitution in terms of promoting the stabilization of glass structure.By introducing Fe/Cr and Ti/Zr nucleating agents,the crystallization of base glass can be promoted and a higher crystallinity can be obtained.The nucleation and crystallization are poor with F/S agents.The major crystalline phases are Diopside and sphene,and the microstructure slightly varies with different nucleating agents.The obtained glass-ceramics have excellent properties with 90 MPa of flexural strength,and chemical durability far superior to that of other common glass-ceramics.
