y (DSC) (Labsys, Setaram, France) in air with a heating rate of 10 ℃ /min from room temperature to 1100 ℃ . The phase of the blastfurnace slag and obtained glass–ceramics were examined by Xray diffraction (XRD) (Model D/MAX3B, RIGAKU, Japan). The samples surfaces were polished and corroded in HF (5 vol%) for 20 s and then observed by scanning electron microscopy (SEM) (Model JSM5610LV, JEOL, Japan). The density of the samples was measured by the Archimedes method. The microhardness was measured by a microhardnesstester (Model HX 1000TM, Taiming, China) with a measuring force of N and a load time 20 s. Samples for bending strength tests with dimensions of 3 mm _ 4 mm_ 30 mm were carefully polished and tested by a universal testing machine (Zwick/Roell Z030, Germany). The chemical resistance of glass–ceramics was tested by a chemical etch method. The samples were corroded in the HCl ( vol%) and NaOH ( vol%) solution for 95 h and then the residual rate was calculated. 3. Results and discussion Table 1 shows the chemical position of blastfurnace slag obtained by Xray fluorescence. The nominal position of the blended mixture is given in . shows the XRD patterns of the blastfurnace slag. It can be seen that the chemical position of the slag involves SiO2, CaO, Al2O3, and MgO as its major ponents. Fe2O3 and TiO2 that act as nucleating agents can greatly enhance the crystallization. Due the presence of Fe2O3 and TiO2, other nucleating agents are not needed. A small amount of gehlenite exists in the amorphous glass( ). The primaryprecipitated phase can act as heterogeneous nucleating centers. In fact, crystallization is favored at the surface of glass particles and primaryprecipitated phase, since nuclei may be formed without the impedance of the surrounding materials, taking into account the volume variation from glass to crystal. the DSC curves of the blended mixture. The small endothermic peak (737–741 ℃ ) indicates the molecular rearrangement in this temperature. The exothermic peak (800–900 ℃ ) corresponds to the crystallization reaction of the glass. With 5 wt% potash feldspar additive, the glass powders have an intense exothermic effect at 840 ℃ , indicating the formation and growth crystals. With more potash。
