英文摘要	Transparent glass ceramics containing xerf(3)-10pbf(2)-90sio(2) (mol%, x = 0, 1, 2) were prepared by the sol-gel method. the thermal behavior of the xerogels was investigated by tg-dta. through non-isothermal experiments, the apparent activation energy for the crystallization of beta-pbf2 phase was evaluated by the kissinger method to be about 162 kj/mol and 167 kj/mol for xerogels with x = 0 and x = 1, respectively, and the avrami exponents lied between 1.5-2.0 for both samples, suggesting that the crystallization of beta-pbf2 phase was a diffusion-controlled process of three-dimensional growth with decreasing nucleation. xrd, tem and eds were carried out to study the evolution of the structure. for sample doped with 1 mol% erf3, it was revealed that few er3+ ions contributed or were incorporated to the beta-pbf2 lattice. they seemed to segregate at the surface of the crystallites and hindered the growth of beta-pbf2 and thus postponed the crystallization.
