摘要
在钠钙硅玻璃的Na^+-Li^+离子交换过程中,熔盐中的阴离子团扩散进入玻璃表面约几百A的深度.这一阴离子团的扩散现象显著改变了玻璃的表面结构,并影响Na^+-Li^+离子交换速度.
In Na^+-Li^+ ion-exchange process, the anion groups of molten salts were found to diffuse into the soda-lime glass surface for several hundreds angstroms. The structure of the glass surface was obviously transformed, and the rate of Na^+-Li^+ ion-exchange was considerably influenced.
