摘要
The results of an experimental investigation into the electrical conductivity for series of alkali silicate glasses with fluoride additives are presented. The inference is made concerning the selective fixation of fluorine in tetrahedra created in a glass by the second glass-former oxide with the formation of the strongly acid ionogenic groups [RO3/2F]M--(+). It is found that the ultimate fluorine content in a homogeneous multicomponent glass is determined by the relationship [F, at. %] less than or equal to [R, at. %].
