| 英文摘要 | Yf3-sio2 glass-ceramic was prepared by sol-gel method for the first time. when the xerogel was heat-treated to 400 degrees c, yf3 crystallites sized around 5 nm were precipitated from the silica matrix and aggregated together to form 50-100 nm congeries particles. with further increasing of the temperature, yf3 crystallites tended to separate from the congeries with their sizes unchanged, resulting finally in a homogeneous distribution among the glassy matrix. the crystallization activation energy of yf3 was evaluated to be 129 and 139 kj/mol by kissinger's method and chen's method through non-isothermal experiments, respectively, implying that the crystallization is controlled by long-range atomic diffusion. the evolution of textural properties of yf3-sio2 glass ceramics with temperature was also investigated mainly through n-2 adsorption experiments.
