Publikováno v: Russian Journal of Applied Chemistry. 93:1518-1524
The temperature conditions of sintering of corundum ceramics affect the rate of subsequent metallization and the catalytic activity of metallized high-porosity cellular material. The process of chemical silvering of the material under study from a so

Silicon-containing Solution for Passivation of Zinc Coatings
Autor: E. A. Zheludkova, N. S. Grigoryan, N. A. Asnis, Tigran Vagramyan, A. A. Abrashov
Publikováno v: Russian Journal of Applied Chemistry. 92:1432-1438
A process was developed for chromate-free passivation of zinc-plated surfaces via formation of conversion silicon-containing coatings on these surfaces. The passivation performed in a solution containing 20–35 g L−1 sodium metasilicate, 0.2–0.5

Study of the Oxidation Rate of Fe2+ Ions in Water during Air Bubbling
Autor: N. A. Asnis, Tigran Vagramyan, Yu. M. Averina, V. V. Men’shikov
Publikováno v: Theoretical Foundations of Chemical Engineering. 52:74-77
The influence of the specific surface area of air bubbles in the process of bubbling on the oxidation rate of Fe2+ ions of model solutions prepared using distilled water with the addition of Fe2+ ions in the form of iron(II) sulfate (pure grade). The
