摘要
FIELD: chemistry.;SUBSTANCE: invention relates to chemistry and can be used as a superionic conductor with a protective layer and a photocatalyst with controlled activity and a protective layer. Method of producing controlled heterostructure Glass/δ*-Bi2O3+Bi2SiO5 includes preliminary mechanical mixing of initial powders, placing them into a platinum crucible, heating to 1,047 °C±20 °C–1,230±20 °C, holding for not less than 15 minutes with further cooling at rate of 3–100 °C/c (first version) or cooling at free speed, without removing from furnace, up to 1,020°C±20 °C–1,047±20 °C, holding for at least 15 minutes and cooling at rate of 3–1,000 °C/s (second version).;EFFECT: invention enables to form two-layer heterostructures (consisting of two types of crystals – δ*-Bi2O3 and Bi2SiO5 and glass) without extraneous impurity phases and contaminants using simple heat treatment, which significantly reduces not only time, but also economic costs for production and enables to easily and simply create material with already specified process properties, changing both ratio between crystalline phases themselves, and "crystal/glass" ratio.;2 cl, 9 dwg
