FIELD: mineral protective coatings.
SUBSTANCE: invention relates to coatings for protection against oxidation during operational heatings in a process of production of high-quality parts and intermediate products from beryllium. Coating is composed of, wt %: Al2O3 3-17, BaO 1-15, CaO 0.5-5, MgO 0.5-5, B2O3 5-10, Na2O 0.5-10, K2O 0.5-5, MgO-Cr2O3 0.5-1, SiB4 1-5, SiO2 the rest.
EFFECT: increased heat resistance and temperature resistance up to 1100°C, and reduced viscosity.
