Effects of Phosphorus and Fluorine on the Crystallization and Structure of CaO-Al2O3-SiO2 System Glass-Ceramic
CaO-Al2O3-SiO2 (CAS) system glass-ceramics were prepared by sintering with certain amount of yellow phosphorus slag.The effects of phosphorus and fluorine on the nucleation,crystallization and structure of CAS system glass-ceramics were investigated by differential thermal analysis,X-ray diffraction,scanning electron microscopy and other measuring methods.Glass-ceramics of CAS system with 42.32wt% yellow phosphorus slag were obtained by nucleating at 615℃ for 1 hour and crystallizing at 926℃ for 2 hours.The results showed that the introduction of phosphorus and fluorine promoted the nucleation and crystallization of glass-ceramics,lowering the crystallizing temperature.The main crystal phase of glass-ceramics was β-wollastonite.The density of the glass-ceramic was 2.695g/cm3.
