METHOD OF OBTAINING HETEROSTRUCTURE, GLASS ENRICHED WITH Si/δ*-BiO/GLASS ENRICHED WITH Bi, IN SYSTEM BiO-SiO Russian patent published in 2019 - IPC C03C4/14 C03B5/08 

FIELD: technological processes.

SUBSTANCE: invention relates to a method of producing a heterostructure, which can be used as a superionic conductor with a protective layer and a photocatalyst with controlled activity. Method of producing heterostructure glass enriched in Si/δ*-Bi₂O₃/glass enriched with Bi, in system Bi₂O₃-SiO₂ includes fast mechanical mixing of initial Bi₂O₃ and SiO₂ components, loading them into a platinum crucible, heating to 1,047±20 °C…1,250±20 °C with holding for at least 15 minutes with subsequent cooling at rate of 10–1,000 °C/s.

EFFECT: obtaining a three-layer heterostructure consisting of two types of glasses and a superionic conductor (δ*-Bi₂O₃), free of impurities and extraneous impurity phases.
