| Abstract: | This paper analyses the effect of different amount of CaF 2 added on crystallization and properties of a Glass-Ceramic with good wear resistance with the aid of X-ray diffraction,differential thermal analysis and scanning election microscopy,and results show that a suitable amount of CaF 2 added promoted the crystallization by forming an intermediate crystalline phase.The optimal amount of CaF 2 was 6wt%. |
