SiO2–Al2O3–CaO glass-ceramics: Effects of CaF2 on crystallization, microstructure and properties
Source abstract
Abstract
Abstract The effects of fluorine content on the nucleation and crystallization behavior of SiO 2 –Al 2 O 3 –CaO glass ceramics system have been investigated. The crystalline phases were determined by X-ray diffraction (XRD). The crystallization kinetics was determined by differential thermal analysis (DTA). The microstructures were examined by using scanning electron microscope (SEM). Fourier transformed infrared spectra (FTIR) analysis was used to study the glass structure. The results showed that by increasing the fluorine content, both the crystallization peak temperature ( T p ) and activation energy ( E ) decreased. Wollastonite, anorthite and gehlenite are the main crystalline phases that exist in the glass ceramics system. The study shows that fluorine promoted initial crystallization of glass and can be used as an effective nucleating agent in the SiO 2 –Al 2 O 3 –CaO system.
