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.
