The interaction of lead silicate glasses С87 & # 8211; 2 and С78 & # 8211; 4 with dilute solutions of hydrofluoric acid has been 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 results obtained are explained by the fact that, along with the formation of soluble salts, complex compounds with limited solubility appear, which, precipitating on the surface, restrain the release of glass components into solution.
