| Abstract: | Using Ni-Ta tailing as the main raw materials, glass-ceramics in which wollastonite is a primary crystalline phase were developed. The basic glass batches are designed based on CaO-Al_2O_3-SiO_2 phase diagram and are optimized by DTA and XRD method. The optimal heating schedule is made by perpendicular methods. The glass-ceramics structure has been studied by XRD and SEM. The chemical and physical properties of glass-ceramics were measured and indicate that the glass-ceramics are more advanced than ceramics tile and natural granite and marble. |
