The 5th issue of the monthly scientific and technical journal "Glass and Ceramics" for 2021 has been published.

Contents of the May issue:

- Investigation of corrosion and scale formation on glass coatings of pipes used in the petrochemical industry

The research of corrosion processes of glass coating of pipes of pipelines in the conditions of acidic, alkaline and marine environments has been carried out. In an acidic environment, corrosion of the pipe coating is insignificant and the corrosion rate is practically absent. In an alkaline environment, the leaching rate is initially insignificant, then sharply increases. In the range of pH = 6 - 12, pipe coatings do not have high durability, and active leaching of the pipe coatings is taking place. Experimental studies have shown that during long-term operation, insignificant scale deposits are observed on the surface of glass coatings of pipes, while a significant layer of scale forms in non-glass-lined pipes.

- Interaction of lead silicate glasses with dilute solutions of hydrofluoric acid

The interaction of lead silicate glasses С87–2 and С78–4 with dilute solutions of hydrofluoric acid is 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.
