The interaction of lead silicate glasses Ñ87-2 and Ñ78-4 with dilute solutions of hydrofluoric acid was investigated. It is shown that an increase in the temperature and concentration of the HF solution does not lead to an increase in the reaction rate. The obtained results are explained by the fact that, along with the formation of soluble salts, complex compounds with limited solubility appear and on precipitating onto a surface prevent the glass components from entering the solution.

硅酸铅玻璃与稀氢氟酸溶液的相互作用

研究了硅酸铅玻璃 Ñ87-2 和 Ñ78-4 与氢氟酸稀溶液的相互作用。结果表明,升高 HF 溶液的温度和浓度并不会导致反应速率的增加。所得结果的解释是,随着可溶性盐的形成,溶解度有限的复合化合物出现并在沉淀到表面时阻止玻璃组分进入溶液。
